C# Sfml i dont see the mistake?

C# Sfml i dont see the mistake? - c#

I dont know why but my jump method does not work. My character can only jump on one single object. The other obstacle haven't any influence on the player. I really don't see my mistake
foreach (RectangleShape obstacles in MoveAtObjectList)
{
MainPlayer.Move(deltaTime, obstacles);
}
foreach (RectangleShape obstacles in JumpAtObjectList)
{
MainPlayer.Jump(deltaTime, obstacles);
break;
}
Draw();
Window.Display();
}
}
}
}
This was part of my main Class, where i call the jump method within a foreach loop. Here in my Payer class I tried to write the jump function.
using SFML.Graphics;
using SFML.System;
using SFML.Window;
namespace Pong3final
{
class Player : RectangleShape
{
float CollisionDistance = 0.5f;
float PlayerSpeed = 50;
float JumpSpeed = 100;
float FallSpeed = 100;
float JumpTimer;
bool JumpBool = false;
bool Fall = true;
public void Jump(float deltaTime, RectangleShape collisionObject)
{
if (Keyboard.IsKeyPressed(Keyboard.Key.Space) && !Fall && CheckCollision(this, collisionObject))
{
JumpBool = true;
}
//Player is jumping
if (JumpBool)
{
JumpTimer += deltaTime;
this.Position -= new Vector2f(0, JumpSpeed) * deltaTime;
if (JumpTimer > 0.5f)
{
JumpBool = false;
Fall = true;
JumpTimer = 0;
}
}
//Player is falling when he doesnt touch anything and he isnt jumping
else if (!CheckCollision(this, collisionObject))
{
Fall = true;
}
//Player is falling
if (!JumpBool && !CheckCollision(this, collisionObject) && Fall)
{
this.Position += new Vector2f(0, FallSpeed) * deltaTime;
if (CheckCollision(this, collisionObject)) //Player stops falling because of a collision with an object
{
Fall = false;
}
}
}
public void Move(float deltaTime, RectangleShape collisionObject)
{
{
Vector2f MovePlayerPosition = Position;
if ((Keyboard.IsKeyPressed(Keyboard.Key.Left) || Keyboard.IsKeyPressed(Keyboard.Key.A)))
{
MovePlayerPosition -= new Vector2f(PlayerSpeed, 0) * deltaTime;
FloatRect collisionOverlap;
if (CheckCollision(this, collisionObject, out collisionOverlap))
{
MovePlayerPosition = MovePlayerPosition + new Vector2f(collisionOverlap.Width + CollisionDistance, 0);
}
}
if (Keyboard.IsKeyPressed(Keyboard.Key.Right) || Keyboard.IsKeyPressed(Keyboard.Key.D))
{
MovePlayerPosition += new Vector2f(PlayerSpeed, 0) * deltaTime;
FloatRect collisionOverlap;
if (CheckCollision(this, collisionObject, out collisionOverlap))
{
MovePlayerPosition = MovePlayerPosition - new Vector2f(collisionOverlap.Width + CollisionDistance, 0);
}
}
Position = MovePlayerPosition;
}
}
public static bool CheckCollision(RectangleShape obj1, RectangleShape obj2, out FloatRect overlap)
{
FloatRect obj1Collider = obj1.GetGlobalBounds();
FloatRect obj2Collider = obj2.GetGlobalBounds();
//Nur die rechte, linke und obere Seite kollidiert
if (obj1Collider.Intersects(obj2Collider, out overlap))
{
return true;
}
overlap = new FloatRect();
return false;
}
public static bool CheckCollision(RectangleShape obj1, RectangleShape obj2)
{
FloatRect obj1Collider = obj1.GetGlobalBounds();
FloatRect obj2Collider = obj2.GetGlobalBounds();
return obj1Collider.Intersects(obj2Collider);
}
}
}

It looks like you are breaking out of your loop after the first iteration, which is resulting in only that first iteration being performed:
foreach (RectangleShape obstacles in JumpAtObjectList)
{
MainPlayer.Jump(deltaTime, obstacles);
break;
}
Remove the break statement from your loop:
foreach (RectangleShape obstacles in JumpAtObjectList)
{
MainPlayer.Jump(deltaTime, obstacles);
}

How and where in the code should I use the loop bool flag to decide if to loop or to make once movement between the waypoints?

The goal is to be able to decide if to loop or to move only once between the waypoints.
I added the loop bool flag for that.
Added the most details I can.
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using UnityEngine;
using UnityEngine.AI;
public class Move : MonoBehaviour
{
public Transform[] targets;
public LineRenderer lineRenderer;
public float speed;
public bool go = false;
public bool countOrigPosAsWaypoint = true;
public bool startFromFirstPositionOnStart = false;
public bool goForward = true;
public bool loop = true;
private List<Vector3> pos = new List<Vector3>();
private List<Vector3> positions = new List<Vector3>();
private int index = 0;
private List<GameObject> objectsToMoveCopy = new List<GameObject>();
// Start is called before the first frame update
void Start()
{
if (lineRenderer != null)
{
pos = GetLinePointsInWorldSpace();
}
else
{
if (countOrigPosAsWaypoint == true)
{
pos.Add(transform.position);
}
for (int i = 0; i < targets.Length; i++)
{
pos.Add(targets[i].position);
}
}
if (startFromFirstPositionOnStart == true)
{
transform.position = pos[index];
}
if (pos.Count <= 1)
{
Debug.LogWarning("Targets list count must be more then 1");
}
}
List<Vector3> GetLinePointsInWorldSpace()
{
positions = new Vector3[lineRenderer.positionCount].ToList();
//Get the positions which are shown in the inspector
lineRenderer.GetPositions(positions.ToArray());
//the points returned are in world space
return positions;
}
// Update is called once per frame
void Update()
{
if (go == true && pos.Count > 1)
{
Moving();
}
}
void Moving()
{
Vector3 newPos = transform.position;
float distanceToTravel = speed * Time.deltaTime;
bool stillTraveling = true;
while (stillTraveling)
{
Vector3 oldPos = newPos;
newPos = Vector3.MoveTowards(oldPos, pos[index], distanceToTravel);
distanceToTravel -= Vector3.Distance(newPos, oldPos);
if (newPos == pos[index]) // Vector3 comparison is approximate so this is ok
{
// when you hit a waypoint:
if (goForward)
{
bool atLastOne = index >= pos.Count - 1;
if (!atLastOne) index++;
else { index--; goForward = false; }
}
else
{ // going backwards:
bool atFirstOne = index <= 0;
if (!atFirstOne) index--;
else { index++; goForward = true; }
}
}
else
{
stillTraveling = false;
}
}
transform.position = newPos;
}
}
If true make a loop between the waypoints either backward or forward and if false just move forward or backward once and stop the last/first waypoint.

I'ld say e.g. at
if (!atLastOne)
{
index++;
}
else if(!loop)
{
stillTraveling = false;
}
else
{
index--;
goForward = false;
}
and accordingly
if (!atFirstOne)
{
index--;
}
else if(!loop)
{
stillTraveling = false;
}
else
{
index++;
goForward = true;
}
And probably remove the current
else
{
stillTraveling = false;
}
as it will be the case most of the time between the points.
In general though: Currently this will all happen in one single frame without any animation... This should probably rather happen in a Coroutine or only do one step at a time .. not in a while loop at all.

How can I move each object in his turn using time to start each object to move?

The goal is to use a time variable for example if the variable int value is 5 then each 5 seconds another object will start moving on the positions.
Now with the loop inside the Move method :
for (int i = 0; i < objectsToMove.Count; i++)
All the objects are moving at the same time but I want to make some kind of queue logic so each N seconds another object will start moving on the positions.
using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using UnityEngine;
public class MoveOnCurvedLines : MonoBehaviour
{
public LineRenderer lineRenderer;
public List<GameObject> objectsToMove = new List<GameObject>();
public float speed;
public bool go = false;
public bool moveToFirstPositionOnStart = false;
private Vector3[] positions;
private Vector3[] pos;
private int index = 0;
private bool goForward = true;
// Start is called before the first frame update
void Start()
{
objectsToMove = GameObject.FindGameObjectsWithTag("New Prefab").ToList();
pos = GetLinePointsInWorldSpace();
if (moveToFirstPositionOnStart == true)
{
objectsToMove[0].transform.position = pos[index];
}
}
Vector3[] GetLinePointsInWorldSpace()
{
positions = new Vector3[lineRenderer.positionCount];
//Get the positions which are shown in the inspector
lineRenderer.GetPositions(positions);
//the points returned are in world space
return positions;
}
// Update is called once per frame
void Update()
{
if (go == true)
{
Move();
}
}
void Move()
{
for (int i = 0; i < objectsToMove.Count; i++)
{
Vector3 newPos = objectsToMove[i].transform.position;
float distanceToTravel = speed * Time.deltaTime;
bool stillTraveling = true;
while (stillTraveling)
{
Vector3 oldPos = newPos;
newPos = Vector3.MoveTowards(oldPos, pos[index], distanceToTravel);
distanceToTravel -= Vector3.Distance(newPos, oldPos);
if (newPos == pos[index]) // Vector3 comparison is approximate so this is ok
{
// when you hit a waypoint:
if (goForward)
{
bool atLastOne = index >= pos.Length - 1;
if (!atLastOne) index++;
else { index--; goForward = false; }
}
else
{ // going backwards:
bool atFirstOne = index <= 0;
if (!atFirstOne) index--;
else { index++; goForward = true; }
}
}
else
{
stillTraveling = false;
}
}
objectsToMove[i].transform.position = newPos;
}
}
}
This is what I tried with InvokeRepeating :
Starting InvokeRepeating in the Start() and cancelled the Move() calling in the Update.
using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using UnityEngine;
public class MoveOnCurvedLines : MonoBehaviour
{
public LineRenderer lineRenderer;
public List<GameObject> objectsToMove = new List<GameObject>();
public float speed;
public bool go = false;
public bool moveToFirstPositionOnStart = false;
private Vector3[] positions;
private Vector3[] pos;
private int index = 0;
private bool goForward = true;
// Start is called before the first frame update
void Start()
{
objectsToMove = GameObject.FindGameObjectsWithTag("New Prefab").ToList();
pos = GetLinePointsInWorldSpace();
if (moveToFirstPositionOnStart == true)
{
objectsToMove[0].transform.position = pos[index];
}
InvokeRepeating("Move", 3f, 0.1f);
}
Vector3[] GetLinePointsInWorldSpace()
{
positions = new Vector3[lineRenderer.positionCount];
//Get the positions which are shown in the inspector
lineRenderer.GetPositions(positions);
//the points returned are in world space
return positions;
}
// Update is called once per frame
void Update()
{
if (go == true)
{
//Move();
}
}
void Move()
{
for (int i = 0; i < objectsToMove.Count; i++)
{
Vector3 newPos = objectsToMove[i].transform.position;
float distanceToTravel = speed * Time.deltaTime;
bool stillTraveling = true;
while (stillTraveling)
{
Vector3 oldPos = newPos;
newPos = Vector3.MoveTowards(oldPos, pos[index], distanceToTravel);
distanceToTravel -= Vector3.Distance(newPos, oldPos);
if (newPos == pos[index]) // Vector3 comparison is approximate so this is ok
{
// when you hit a waypoint:
if (goForward)
{
bool atLastOne = index >= pos.Length - 1;
if (!atLastOne) index++;
else { index--; goForward = false; }
}
else
{ // going backwards:
bool atFirstOne = index <= 0;
if (!atFirstOne) index--;
else { index++; goForward = true; }
}
}
else
{
stillTraveling = false;
}
}
objectsToMove[i].transform.position = newPos;
}
}
}

int i = 0;
void StartMove()
{
i = 0;
InvokeRepeating(nameof(Move), 3f, 0.1f);
}
void Move()
{
if( i < objectsToMove.Count)
{
Vector3 newPos = objectsToMove[i].transform.position;
float distanceToTravel = speed * Time.deltaTime;
bool stillTraveling = true;
while (stillTraveling)
{
Vector3 oldPos = newPos;
newPos = Vector3.MoveTowards(oldPos, pos[index], distanceToTravel);
distanceToTravel -= Vector3.Distance(newPos, oldPos);
if (newPos == pos[index]) // Vector3 comparison is approximate so this is ok
{
// when you hit a waypoint:
if (goForward)
{
bool atLastOne = index >= pos.Length - 1;
if (!atLastOne) index++;
else { index--; goForward = false; }
}
else
{ // going backwards:
bool atFirstOne = index <= 0;
if (!atFirstOne) index--;
else { index++; goForward = true; }
}
}
else
{
stillTraveling = false;
}
}
objectsToMove[i].transform.position = newPos;
i++;
}
}
Try this one might help you. Here What I did is to remove the for() loop and instead use an if() condition this way You move function will only execute one time only for one object each time Move() get called by InvokeRepeating(). Nove Call StartMove() where/when you want to start moving the objects.

Prefabs of mobs in the game on Unity do not go on the phone

There was a very interesting error with game characters, on the first level they walk quietly and everything is OK, and on the second they go only in the editor, and after compilation they are no longer there. Ai navigation exists. The character must find ... by the tag maybe he is on stage. What could be the problem? error only at the second level and only after assembly

Trying to generate prefabs over and over in semi-random positions

So I made this code in an effort to start making a script that generates bush objects in my scene randomly, however when in runs it only spawns the first bush. Here is the code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class BushSpawner : MonoBehaviour
{
public GameObject bush;
private float x = 0f;
private float y = -.47f;
private float z = 0f;
private int bushCount = 0;
private Vector3 origPos;
private bool xPlus = false;
private bool xMinus = false;
private bool zPlus = false;
private bool zMinus = false;
// Use this for initialization
void Start()
{
SpawnBushes();
}
// Update is called once per frame
void Update()
{
}
void SpawnBushes()
{
Vector3 startPos = new Vector3(x, y, z);
Instantiate(bush, startPos, Quaternion.identity);
bushCount += 1;
while (bushCount < 100)
{
Vector3 checkPos = new Vector3(x, y, z);
Collider[] intersecting = Physics.OverlapSphere(checkPos, 1f);
if (intersecting.Length == 0)
{
//code to run if nothing is intersecting as the length is 0
Instantiate(bush, checkPos, Quaternion.identity);
bushCount += 1;
}
else
{
//code to run if something is intersecting it
RollPos();
}
}
}
void RollPos()
{
if (xPlus == true
&& xMinus == true
&& zPlus == true
&& zMinus == true)
{
int newRoll = Random.Range(1, 4);
if (newRoll == 1)
{
x += 10f;
}
else if (newRoll == 2)
{
x -= 10f;
}
else if (newRoll == 3)
{
z += 10f;
}
else if (newRoll == 4)
{
z -= 10f;
}
xPlus = false;
xMinus = false;
zPlus = false;
zMinus = false;
}
else
{
int roll = Random.Range(1, 4);
if (roll == 1)
{
if (xPlus == false)
{
x += 2f;
xPlus = true;
}
else
{
RollPos();
}
}
if (roll == 2)
{
if (xMinus == false)
{
x -= 2f;
xMinus = true;
}
else
{
RollPos();
}
}
if (roll == 3)
{
if (zPlus == false)
{
z += 2f;
zPlus = true;
}
else
{
RollPos();
}
}
if (roll == 4)
{
if (zMinus == false)
{
z -= 2f;
zMinus = true;
}
else
{
RollPos();
}
}
}
}
}
I tried putting SpawnBushes in Update to run while a bool is true then make it false when SpawnBushes is done, but that creates the first bush, then 99 other bushes in one random position next to it.
If someone can point me in the right direction or tell me I'm completely off-base I would appreciate it immensely!

Ron Beyer pointed out that I didn't have a large enough range in my Random.Range in RollPos(). Thanks again Ron!

Only one gameobject being affected by script

Making a state machine AI "game" I have 3 states Movement, Combat, and View. They all work very well, now I'm making a flee (by the way if anyone has any good links to tutorials or info that they have off hand I would love that) state so I want to make all three previous state in their Idle mode. Which works perfectly when I have 1 AI. As soon as I put the rest (there is 6 total now) it will still only affect 1, but then after some time it will "release" I guess it the best term the script and just goes back to the three states that are supposed to be idle. I think that in my Coin script I am saying find and I think it needs to be something else, I'm just not sure if that's even right but based off of my previous experiences that's usually the case with Unity. I'll post some code, but here's some info that may help your eyes by not having to read through everything:
-I have a bool set up in my AIClass that is false until one of my gameobjects collides with a 'coin', and coin is jsut a gameobject i put in my game to test out my AI behaviors. When that bool is true, in my update in my AIClass(sorry it's at the very bottom of the script you can scroll down, but I had to put other code just in case I was doing something in that to cause my problem.) It sets the state of MovementState to Idle, CombatState to Idle and ViewState to Idle.
-Also, when that bool is false is the only time that the call for the transition of states occur. For example, normally the AI will search around trying to find player, if they find him they go near him, and if they are in a certain distance they fire. Pretty simple. The movement between those states happens at the end of each IENumerator when the 'NextMovementState()' or 'NextCombatState()' or 'NextViewState()' are called. So when the bool is true those should never be called, halting the AI from moving to another state other than Idle (to what it's set at when the bool is true in the update).
And this works fine when I have only 1 AI in the game.

You can use GameObject.FindObjectsOfType() or GameObject.FindGameObjectsWithTag

you can do that with store all the AIClass into array and then loop it become specific, so every enemy can affected
AIClass[] AIObject = GameObject.Find("Enemy").GetComponents<AIClass>();
foreach(AIClass a in AIObject ){
//do something with a
}
it should work.
