java - libgdx remove bullet from bullet array -

im creating 2d game. have array of bullet class use create bullets. have array consisting sprites move around screen being rendered every 3 4 seconds.

problem:

when bullet , other sprite meet @ same location bullet should removed or deleted , never comeback.

please me...

code rendering bullet:

bullet.java:

import com.badlogic.gdx.math.vector2;  public class bullet{  public vector2 bulletlocation = new vector2(0, 0); public vector2 bulletvelocity = new vector2(0, 0);  public bullet(vector2 sentlocation, vector2 sentvelocity) {     bulletlocation = new vector2(sentlocation.x, sentlocation.y);     bulletvelocity = new vector2(sentvelocity.x, sentvelocity.y); }  public void update() {     bulletlocation.x += bulletvelocity.x;     bulletlocation.y += bulletvelocity.y; } }   

main class:

arraylist<bullet> bulletmanager = new arraylist<bullet>(); array<other> othersmanager = new array<other>(); bullet currentbullet; other currentothers; 

render();

int other = 0; while (other < othersmanager.size) { currentothers = othersmanager.get(other);         if (currentothers.otherlocation.x > guy.getx()) {             currentothers.othervelocity.x = -2f;         }         if (currentothers.otherlocation.x < guy.getx()) {             currentothers.othervelocity.x = 2f;         }         currentothers.update();         others.setposition(currentothers.otherlocation.x,currentothers.otherlocation.y);         others.draw(batch);         other++;     }      int counter = 0;     while (counter < bulletmanager.size()) {         currentbullet = bulletmanager.get(counter);         currentbullet.update();         shoot.setposition(currentbullet.bulletlocation.x,currentbullet.bulletlocation.y);         if(currentothers.otherlocation.x == currentbullet.bulletlocation.x){             bulletmanager.remove(currentbullet);         }         shoot.draw(batch);         counter++;     } 

it seems problem in block of code:

    if(currentothers.otherlocation.x == currentbullet.bulletlocation.x){         bulletmanager.remove(currentbullet);     } 

i suggest use epsilonequals method vector2 class check whether currentothers.otherlocation matches currentbullet.bulletlocation:

    if(currentothers.otherlocation.epsilonequals(currentbullet.bulletlocation)){         bulletmanager.remove(currentbullet);     } 

moreover can use epsilonequals float epsilon: documentation
