How to enable extended unit limits?

hi,

When I host a map on Battle.net, there is a radio button to enable Extended unit limits. This allows maps to go past CCMU.

But not all maps can do this. Some games I host the option is grayed out.

How does a map enable extended unit limits?



None.

If the map uses EUDs, it won't support extended limits.

So I have to remove all my EUD triggers?



None.

I think I've heard some EUD conditions won't take away the extended unit limits. All EUD actions do.

What's the problem though? I can't understand. The units array is bigger -- but since they're emulating addresses anyway what is the problem to map EUD actions differently?



Some.

My understanding is any EUD conditions present cause the unit limits to be disabled - e.g. I read some text with EUDs in helms deep for the drop-banners, unit limits cannot be extended due to this.

In theory it's entirely possible for them to emulate with the larger arrays present - just map the higher indexes to a new address space and publish that - but that's not what they originally set out to do with EUDs - support existing EUD maps - and it's also a problem of greater complexity and development time, esp. given that they won't have the test maps already setup for them, so EUD maps are, at least for now, locked to the original limits.

So unfortunate..

EUD actions too, even since they are disabled (as actions) under a trigger with condition Never. :(

I see you !

My understanding of the problem is that there are maps which iterate over the units array / images array / sprites array. With extended limits you have units outside of the iteration. There are also maps which iterate over linked lists of units / s[rites / images, and the linked lists are emulated, but the array bounds in EUD space alias so the emulator can no longer determine if unit 2000 is meant or image 20.

What blizzard would need to do is define completely new base addresses for the arrays which do not alias, but that means the maps would need to be remade to use these new base addresses, and the emulator would need to know if the map is using old or new offsets. So not very practical.

Why are you using QWERTY keyboard layout? For programming?
