Embedded script run multiple times each frame
Posted: Sun Oct 16, 2005 6:32 pm
In doing a little debugging on my embedded scripts, I noticed something I thought was pretty strange. For each frame, the script is executed a minimum of 3 times (including during normal playback or using the buttons to go one frame at a time), often 6 if you drag the pointer on the timeline. And, if you hold the mouse button down after having dragged on the timeline and the mouse moves even a tiny bit (even if you are on the same frame) it runs through another set of 3 iterations. Now, I know the embedded scripting is still experimental (but really cool), it seems if you do something complex, or have a bunch of them, it could get a bit costly.
But more of a question that it brought up: is it just the embedded script interface, or is Moho evaluating everything for every frame that it renders during playback. Unless that's something that Moho has to do, it seems like it could easily explain the sluggish playback as scenes become more complicated.
I made 2 little embedded scripts to display this.

Put them on any 2 layers in a project and you can see exactly what I'm talking about. Just thought it would be worth pointing out.

Code: Select all
function LayerScript(moho)
local frame = moho.frame
if frame == 0 then
oldframe = 0
oldframecount = 1
print("Resetting")
end
endCode: Select all
function LayerScript(moho)
local frame = moho.frame
if oldframe == frame then
oldframecount = oldframecount + 1
else
oldframe = frame
oldframecount = 1
end
print("Frame#",frame, "Frame interations",oldframecount)
end
