Die behavior with animation

[nighca]

As mentioned in #314 , if we call die of cloned sprite, its scripts / coroutines will be stopped.

For sprite with code below:

onCloned => {
	for {
		wait 0.1
		println "im alive"
	}
}

onCloned => {
	show
	wait 1
	println "call die"
	die
}

onStart => {
	clone
}

We'll get output like this:

✗ gop run .
im alive
im alive
im alive
im alive
im alive
im alive
im alive
im alive
im alive
call die

But if there's a dying animation, which requires some time to play, we'll get output like this:

✗ gop run .
im alive
im alive
im alive
im alive
im alive
im alive
im alive
im alive
im alive
call die
im alive
im alive
im alive
im alive
im alive
im alive
im alive
im alive

Game developers may perform more complex actions than just println "im alive", potentially affecting overall game behavior. They will have to maintain their own isDead state to avoid mistakes:

var isDead bool

onCloned => {
	for {
		wait 0.1
		if isDead {
			break
		}
		println "im alive"
	}
}

onCloned => {
	show
	wait 1
	println "call die"
	isDead = true
	die
}

onStart => {
	clone
}

It is advisable to adjust SPX behavior to lessen the burden on game developers. We could stop scripts / coroutines when die is called, rather than waiting for the animation to finish.

Please share your ideas here, @xushiwei @JiepengTan.
