My map got pretty heavy delay

is there any particular reasons that cause delay ?

I don't think it's the internet connection, because I didn't get delay when I play other maps

so is it because of script, or version ? I have patch 1.24b but my friends (maybe) have patch 1.24.

I know the informations I provided is not enough, but if you know something, anything, please help

I will provide the map (or script) if needed.

sorry if I have posted in the wrong forum

If you can play together at all, you probably all have the same patch. If not, just log on to bnet and you'll update automagically.

It's probably either a trigger or a ton of models. If you don't have a ton of things placed on your map, start disabling triggers until the map speeds up, and then figure out which one was causing the lag.

so it's the script ? I don't think I have ton of models, well, I have imported many but not that many, my map's size is 2.4MB, after optimizing is 1.5MB

it would be troublesome for me to disable some triggers, well, I don't think my map can run property with some disabled triggers

I attached the non-protected map, if you can help, please have a look. I will greatly appreciate your help (if it works out, you will, ofc, have credit in my map)
thank in advance.

Arrow key commands are notoriously slow in Battle.net play; that could be the issue.

I didn't use any Arrow key command :|

bump

I don't care if your map runs "properly". You can turn the triggers back on after you isolate which one(s) is(are) causing lag and fix the problems in them.
Get cracking!
