AndEngine GLES2-在Entity.java中的IndexOutOfBoundsException:1402

Question

我有以下错误,我不知道:

我相信它与我在代码中使用的MoveModifier中的onManagedUpdate()有关.

Answer 1

这几乎总是由于在错误的线程中分离实体.检查您可能在响应用户交互或在Modifier回调中分离实体的任何位置,并将其包装runOnUpdateThread.例如:

@Override
public void onModifierFinished(IModifier<IEntity> pModifier, IEntity pItem) {
    engine.runOnUpdateThread(new Runnable() {
        @Override
        public void run() {
            widget.detachSelf();
        }
    });
}
