java - inputprocessor touch down gives late response? -

so busy kind of pong game android. have paddle , ball. controls player (the paddle) followed:

• if player touches on left side of screen, paddle goes left
• if player touches on right side of screen, paddle goes right

actually above 2 points work fine, bothers me, when im holding right right finger, , after release , fast holding left left finger, paddle executes 1 time "going left", , stops, while still holding left. (and vice versa)

i discovered happens if use 2 fingers. if im holding down right finger, , try go fast press other side, doesnt stop , keeps going left.

but important use 2 fingers, since way how game should played.

this may explained unclear, can ask in comments more specific questions.

i think problem resides in fact have touchdown boolean being shared between left , right sides. if press left side fast enough, touchdown left finger gets set true before touchdown right finger set false, making them false. try instead:

package com.nahrot.teleportball;  import com.badlogic.gdx.gdx; import com.badlogic.gdx.inputprocessor; import com.badlogic.gdx.math.vector2;  public class myinputprocessor implements inputprocessor {     public vector2 lefttouchpos = new vector2();     public vector2 righttouchpos = new vector2();     public boolean touchleft = false;     public boolean touchright = false;      @override     public boolean keydown(int keycode)     {         return false;     }      @override     public boolean keyup(int keycode)     {         return false;     }      @override     public boolean keytyped(char character)     {         return false;     }      @override     public boolean touchdown(int screenx, int screeny, int pointer, int button)     {         if(sidetouched(screenx, true))     {              touchleft = true;             lefttouchpos.set(screenx, screeny);     }     if(sidetouched(screenx, false))     {         touchright = true;         righttouchpos.set(screenx, screeny);     }         return false;     }      @override     public boolean touchup(int screenx, int screeny, int pointer, int button)     {         if(sidetouched(screenx, true))         {              touchleft = false;     }     if(sidetouched(screenx, false))     {         touchright = false;     }         return false;     }      @override     public boolean touchdragged(int screenx, int screeny, int pointer)     {         return false;     }      @override     public boolean mousemoved(int screenx, int screeny)     {         return false;     }      @override     public boolean scrolled(int amount)     {         return false;     }      private boolean sidetouched(int x, boolean checkleft)     {     if(checkleft)     {         if(x <= gdx.graphics.getwidth() / 2)             return true;     }     else     {         if(x > gdx.graphics.getwidth() /2)             return true;     }     return false;     } } 

here, separated booleans , vectors left side , right side, , made convenience function checking whether touchdown or touchup on right or left side of screen, , adjusted corresponding booleans , vectors accordingly. assume vector needed check side pressed anyway, suspect work need 2 booleans sides touched. code untested, way, should idea if doesn't work.
