I'm trying to render something on a certain event, and I don't know how to do this. I can't put the renderer in the event because of needing to extend the Render class, so How do i do this?

You could just use plain old booleans to check if the time is right.

if (#) {
//special time to render
}
else {
//normal render
}

You can flip-flop them also, but that's your decision.

 

I bet you can find your own way around this, as this isn't that efficient.

To clarify CoolBoy's suggestion what you need to do is:

  1) Set a boolean in response to the event, in the event handler method.

  b) in the regular renderer check that boolean and render accordingly.  If you didn't already have a renderer then you need to create one.

 

In other words, you don't call a render, rather you let the renderer be called naturally and check whether it should do something special.

 

Other note: the rendering happens on the client side only, so the boolean has to be available on the client side.  If that boolean is set on the server then you will need to sync the client somehow (with packet or similar).

And where do I run the rendered from?
