如何在 libGdx 中创建自定义侦听器？

Question

How do I create my own EventListener? I need a specific event to happen when a variable reaches a specific value.

I do not know what information still needs to be given

Answer 1

You don't need EventListener for this. You can simply check it in render() function if it is enough to check value each time frame is rendered.

If this isn't enough, you will have to create your own class, which implements setter, which checks if new value matches your condition and executes event.
