Entity couldn't be removed after removing the component

[chengenzhao]

Hi:

I just have a problem of removing the entity, following code doesn't work properly

and if we delete the entity.removeComponent part(top 3 lines)
then entity could be removed from the world
but if we remove the component first
then the removedFromWorld method doesn't work

Hi,

I can't see anything wrong with the code above. Please can you provide a minimal example that reproduces the issue.

The problem code is in
com.whitewoodcity.battlefxgl.entity.component.components.DestroyableComponent
comment out stopEntity method
and uncomment entity.removeComponent
then start the game
you may see the error
The Tank, Launcher could have such problem
if the player destroy the Tank, it wouldn't be remove from the world
The player could jump and stand on the invisible tank or launcher

There is a tank will spawned after 10 seconds of the game
so dont rush into the right
just be patient, the Tank will rush into the left where the player stands
and you may change the spawn seconds in the class file:
com.whitewoodcity.battlefxgl.Game
onUpdate method

int delay = 600;//10 seconds

  @Override
  protected void onUpdate(double tpf) {

    delay--;
    if(delay==0){
      spawn("TankM7", gameWidth-300, 400);
    }

will have error like:

If there are too many enemies rush out then just comment out following codes in onUpdate method of Game.java

if ((int) (Math.random() * 600) == 0) {
      switch (FXGLMath.random(0,10)) {
        case 0 -> spawn("TankM7", gameWidth-300, 100);
        case 1 -> spawn("Apache", gameWidth-300, 100);
        case 2 -> spawn("Launcher", gameWidth-300, 100);
        case 3 -> spawn("Yamato", gameWidth-300, 400);
        default -> spawn("F3",
          new SpawnData(gameWidth - 200, player.getY() - 400)
            .put("targetX", (int)player.getX())
            .put("targetY", (int)player.getY()));
      }
    }
