Game speed
- This page is a stub. You can help out by adding more information.
I'm recreating a page here that seems, from all I can tell, to have previously existed prior to the recreation of the Wiki in March 2015 to flush out the spammers that had formed a hostile takeover. I've never seen the page before and the following are just my empirical observations from a test map in SC.
Frame time is in direct sync with game time; game speed alters game time. Game time on Fastest is roughly 1.50x realtime, but it seems to vary slightly as in SC2. Gamespeed normal varies a bit from 1.00x realtime as well. Using Wait(0) Hypers, ie every other frame of animation, Starcraft runs a trigger cycle 8 times every game second. From this we can extrapolate that there are 16 frames of animation per game second. Regular non-hypered trigger check interval is at 31 out of 32 frames. Therefore, there are 31 frames per trigger check on normal trigger cycle speed.
Regular Trigger Cycles
1 Tick * 1000 ms * 1 Trigger Cycle = 1000 Trigger Cycles ≈ 0.8 Hz 42 ms 1 Second 31 Ticks 1302 Seconds
Hyper Trigger Cycles
1 Tick * 1000 ms * 1 Trigger Cycle = 1000 Trigger Cycles ≈ 11.9 Hz 42 ms 1 Second 2 Ticks 84 Seconds
Single Tick Hypers
1 Tick * 1000 ms * 1 Trigger Cycle = 1000 Trigger Cycles ≈ 23.8 Hz 42 ms 1 Second 1 Tick 42 Seconds
Game Seconds
1 Tick * 1000 ms * 1 Game Second = 1000 Game Seconds = 125 Game Seconds
42 ms 1 Second 16 Ticks 672 Real Seconds 84 Real Seconds
First trigger cycle occurs when elapsed game ticks equals 2
"Note that game seconds (as seen in conditions like elapsed time) increment every 16 ticks, and regular trigger cycles occur every 31 ticks, this causes unintuitive behavior where some ""elapsed time exactly"" triggers will run and some won't as well as tricky to align time/trigger cycle values"
Regular Trigger Cycle Tick Game Time 1 2 0 2 33 2 3 64 4 4 95 5 5 126 7 6 157 9 7 188 11 8 219 13 9 250 15 10 281 17
