The Dink Network

> the actual amount of frames waited might be shorter.

Indeed it is for yedink and other old dinks. However I believe that Seth has messed with the timing system on his end so that the frame-draw time is explicitly locked, so it doesn't apply for most users.

It appears that when a script callback is added to the callback list by running wait() etc it is added with no "timer" value (i.e. the time to wait) which is only calculated a frame later. This is the same for all engines!

You can see this in action in yedink while it's looping by opening the callbacks window and then setting it to pause on every frame, then stepping through by unpausing. The timer value will flip-flop between zero when it hits the wait, and then a game tick some time in the future.

I did a little test by adding the line

callback[k].timer = game_GetTicks() + callback[k].min;

to scripting_add_callback() so that when a wait is triggered and the callback added to the list, it sets the initial timer value meaning it gets run on the next frame, rather than waiting to calculate a value, which ends up running things as one would expect them to, and you get a debug line each pframe:

This means I was wrong in the top post somewhat, but it is odd that it's not like this by default.
Also what did redink1 do to the emojis?
