Lag issue

RobertMKD · Feb 14, 2015

On my tower defense map, there's a terrible lag when there's more than 70 units spawned on the map, there was no lag before, even when 200 units are spawned.. any idea why's this happening?

Wietlol · Feb 14, 2015

I know why. Because you create units.

Really what did you expect as answer if we have only this few information?
Some issues are pretty unique and have only a few known causes but "Lag issue" is very broad.

You can debug yourself or you can upload map here for us to try to help you fix. If you want to debug it yourself then investigate the matter one by one finding who is the culprit. It sounds like high-poly models though which means like rips/exports from another game that are too graphically intense to be rendered easily which then costs a lot of power from peoples computers. However it might not be that, try checking through triggers first.

RobertMKD · Feb 14, 2015

Well, I have two long triggers, it's about the creep waves messages and changing the unit type for each wave.. but it's just 'display message' and 'set variable', it can't be the reason for the lag when more than 70 units are spawned?

Tal'Rarity · Feb 14, 2015

Do you clean up the point leaks?

RobertMKD · Feb 15, 2015

you mean destroy the location? if so, yes i did.

Alright · Feb 15, 2015

Post your triggers.

RobertMKD · Feb 15, 2015

how do i post my triggers?

Waits should be "Wait (...) seconds of gametime" if you do not want to use timers.

If spawn 1 <gen>, spawn 2 <gen> etc are very small, you should set the location variables to the center and use that one over and over again instead of making a new one every time.

Also never use wait or wait gametime in loops.
Make a timer and start the timer when you want to spawn the units.
Event -> Elapsed gametime = 29 seconds.
Action -> Start CreepSpawnTimer as repeating with 1 second.
Make a new trigger, When CreepSpawnTimer expires, create the units and set an integer +1.
When the integer reaches 30, you can stop the timer to stop the spawn... or whatever you wanted to do.

More than that, I cannot see.

RobertMKD · Feb 15, 2015

Still lags, but now it lags when more than 130 units are spawned..

maddeem · Feb 15, 2015

One major problem with warcraft 3 is any order that makes a unit move. This causes the unit to recalculate its path through the terrain, which is very costly performance-wise. Which I assume you are using as this can easily cause lag with as little as 50 units being ordered every second.

This may or may not be the case, however you should post your map. Don't fret about someone stealing your map; they won't.

RobertMKD · Feb 15, 2015

I've been opening other td maps to study them and learn making my own, on those maps, there's even more triggers and units, but it still doesn't lags, while my map lags :/

I'm using regions to move the creeps. When a unit owned by the player of the creeps enters a corner, the unit moves to other corner.. I think it's the same with all other td maps

Wietlol · Feb 15, 2015

Upload your map.
I have made some difficult route stuffs myself too... and almost none of 'em lagged.

Dr Super Good · Feb 16, 2015

Waits should be "Wait (...) seconds of gametime" if you do not want to use timers.

Except that action leaks a handle pointer.

The most likely cause is that the units have not been pre-loaded so the game stalls for I/O to load the unit's assets. This only happens some times because the OS will cache asset data and the game might cache the actual loaded assets. Using a preloader to read all WC3 data into memory should reduce the length of the stall. Placing one unit of each wave on the map so that they get loaded at map initialization (during load screen) will completely remove the stalls at the cost of slightly longer map load time.

If your map has generally low frame rate continuously then this is not the case. Asset stalls will be once off spikes at the start of every new wave.

If the problem is generally low performance when 70 units are on the map then there is something running with a unit based complexity that consumes a lot of resources. For example massive area damage, badly written unit search triggers, high frequency unit polling triggers, various abilities with huge area etc.

At least it fixes the problem of paused game...
I don't want to bother him with systems and stuff to simply replace the wait and also told him how to do it with timers... now it is his choice.

I think I already showed you my own PolledWait()...

RobertMKD · Feb 16, 2015

I replaced the first wave with not modified units, and it still lagged.. I guess it's something with the triggers, cause it didn't lagged before, but when I added new triggers, it started lagging, I'll try to find the source..

Wietlol · Feb 16, 2015

Upload the map... I am quite curious what it is.

RobertMKD · Feb 16, 2015

I've solved my problem!! I've just figured out that I didn't changed the 'wait' action to 'wait (game-time)' for the wave messages trigger, I did that and now the map doesn't lags when even 200 units are spawned!!

Thank you all for helping me!!

@DSG
Am I missing something or is ^^^that^^^ supposed to actually reduce performance?

I mean... yes I told him to change it but a WaitTimer (PolledWait) uses a SleepAction itself...

EDIT: I think that it was not laggin' but rather has a delay between the spawn and display... I don't know of any other explanation myself.

RobertMKD · Feb 16, 2015

Actually, it was a trigger that was performing actions every 0.01 seconds.. that's why my map lagged, I deleted it now

I love to make triggers that causes massive laggs but are totally useless and do nothing functional so I can remove them whenever I want... I think we are on the same level
