RE: PATCH: true C coroutines -- yield across C stack from anywhere

["Jean-Christophe Capdevila" <jccapdevila@...>]

Hi!

Yeah it will work...

But i wiil be pain in the ass for gamedesigners to script an object..

Ex: 

I want:

	While true do

		Goto(WayPointA)
		Goto(WayPointB) 	
		Goto(WayPointC)
		Goto(WayPointD)	
		PlayAndWaitAnim("dummyanim")
	end

Goto & PlayAndWaitAnim automatically yields if necessary...


with your solution it will be :

	While true do

		while Goto(WayPointA) do
 		end
		while Goto(WayPointB) do
 		end
		while Goto(WayPointC) do
 		end
		while Goto(WayPointD) do
 		end
		while PlayAndWaitAnim("dummyanim") do
 		end
		
	end

not really "friendly" for poor gamedesigners....

but thanks...

JC

Could you just do:

 while WaitEvent() do
 end

...? So your C function returns true if it wants WaitEvent to be called
again, 
and false if it wants execution to continue?
