[Solved] Player Group leaks

[SpasMaster]

Hello Hive!

I have a question regarding a specific memory leak: the Player Group leak, that is cleaned with Custom script: call DestroyForce(udg_PlayerGroup)
I was surprised that I never knew these leak, so my question is what is their significance? Are they equally bad as the other leaks such as location and unit group leaks? I just need a bit of information regarding this type of leaks. Thanks!

PlayerGroups (aka Forces) can leak momory just like other handles can.
UnitGroup leaks may maybe be a worse leak in some case, if there is a difference
it's not important to know exact numbers. One just should know that they should be prevented.

I understand. I still can't believe that I never knew Player Groups leak. Suddenly, some Memory Crashes start to make sense. I was sure I had the vast majority of leaks cleaned. Now it turns out there is a bunch of them! Thanks for the information.

You're welcome.

However, memory leaks usually don't lead to instant crashes, but more lead to unfluent gameplay,
if the amount is enormous. But they still should be removed as rule of thumb.

One never learns out I guess - happy removing.

Force leaks are slightly worse than location leaks but better than group leaks. Group leaks can contain several dozen units, while forces are limited to at most 16. Locations should not have dynamic sizes so should be the smallest.

As far as which usually causes the most damage it is group followed by location then force. Forces are seldom created in comparison to the other two.

Leaks will usually render a map unplayable (<1 FPS) long before the game crashes. There are a few exceptions where finite resources are depleted. An example is units and destructibles which will crash the game after ~40,000-60,000 are present on the map.

Someone needs to say it ....

(All Players) does not leak. Only special player groups leak. All players is a native global or some crazy tech language like that. It means that reference is always there and never needs to be destroyed. (All players matching are an enemy of Player 1) will leak a force.
