While Loop Issues

So I want my AI to move to a certain point based on the player's position which is called in update so I used a while loop but when the AI is almost there the game freezes.

Code (CSharp):

1. public void MoveToLeftNodeOnPlatform()
2.     {
3.         Vector3 leftNode = controller.objectStandingOn.GetComponent<Ground>().leftNode;
4.  
5.         while(transform.position.x >= controller.objectStandingOn.GetComponent<Ground>().leftNode.x)
6.         {
7.             SetDirectionalInput(new Vector2(-1, 0));
8.         }
9.  
10.         SetDirectionalInput(new Vector2(0, 0));
11.     }

Thank You

 

definitely looks like an infinite while loop situation, but there's not enough context really to tell why the condition is always true.

What does SetDirectionalInput do?
What is Ground.leftNode? Does it change?
Does transform.position change?

 

SetDirectionalInput is a function that set the input that moves the enemy
Ground.leftNode is the left most position on the ground, it does not move
transform.position will change when SetDirectionalInput is not Vector2.zero

 

You may want to post your setDirectionalInput as well as I agree, it sounds like you're hitting an infinite loop somewhere.

 

Code (CSharp):

1. public void SetDirectionalInput(Vector2 input)
2.     {
3.         directionalInput = input;
4.     }

what it is used for in PLAYER'S function:

Code (CSharp):

1. void Update()
2.     {
3.         Vector2 directionalInput = new Vector2(Input.GetAxisRaw("Horizontal"), Input.GetAxisRaw("Vertical"));
4.         player.SetDirectionalInput(directionalInput);
5.  
6.         if (Input.GetKey(KeyCode.Space))
7.         {
8.             player.OnJumpInputDown();
9.         }
10.         if (Input.GetKeyUp(KeyCode.Space))
11.         {
12.             player.OnJumpInputUp();
13.         }
14.     }

 

It looks like your "SetDirectionInput" function sets how far the object should move when it does move, but it does not make the object move right away. If that's the case, you keep setting the direction inside the while loop, but you never give the object a chance to move so the condition is always true and it keeps looping.
