Question by Rise2 · Feb 24, 2018 at 07:47 PM · movement scriptcharacter movementbutton trigger eventsleftright

Character direction can't be changed before the character reaches a screen limit in some cases

Hello everyone!

So I have t$$anonymous$$s player that goes from left to right when I $$anonymous$$t the "right" button, and it goes from right to left when I $$anonymous$$t the "left" button. When I $$anonymous$$t the "left" button, I can press the "right" one right away and the player will change directions on the spot. On the other hand, if I press the "right" button, I can't change the player's direction before the player gets to the right limit.

Here is an image showing the situation:

Here is my script w$$anonymous$$ch is attached to the player:

 private bool leftbutton;
 private bool rightbutton;

 private float x;
 public float speed;
 public float y;

 private Vector3 vectorDir;

 //function when "left" button is clicked
 public void Left()
 {
     if (transform.position.x > -2.0f)
     {
         leftbutton = true;
     }
 }

 //function when "right" button is clicked
 public void Right()
 {
     if (transform.position.x < 2.0f)
     {
         rightbutton = true;
     }
 }

 void Update()
 {

     vectorDir = new Vector3(x, y);
     transform.Translate(vectorDir * speed * Time.deltaTime);

     if (leftbutton == true)
     {
         x = -1.0f;
         if (transform.position.x <= -2.0f || rightbutton == true)
         {
             leftbutton = false;
         }
     }

     if (rightbutton == true)
     {
         x = 1.0f;
         if (transform.position.x >= 2.0f || leftbutton == true)
         {
             rightbutton = false;
         }
     }

     if (rightbutton == false && leftbutton == false)
     {
         x = 0.0f;
     }

 }

Any help is greatly appreciated!

t$$anonymous$$s part:

  if (leftbutton == true)
  {
      x = -1.0f;
      if (transform.position.x <= -2.0f || rightbutton == true)
      {
          leftbutton = false;
      }
  }

if rightbutton is true, leftbutton will immediately set to false in update :P maybe you can take an other construct, for example you can take an int with value 0 = stop, 1 = left, 2 = right, and set the int when you $$anonymous$$t a button.
