Build failure - The Moirai have given mortals hearts that can endure.

Could you upload a short video of the behavior? So people can have an idea of what's going on without having to download and compile everything themselves.

I'm going to make a forum post about D53, one about this (since in my mind it should get committed alongside D13) with some SVN / patched videos, and some more details. The idea will be to get some playtests as well.

Some footage.
This is SVN: https://www.youtube.com/watch?v=QQC2wrIUHLQ
You can see that the units move around the phalanx formation, the movement around the tree is wonky, and there is a lot of collisions when they return resources.
This is with D13 and D1490: https://www.youtube.com/watch?v=aRfP7lA1m7Y
You can see that the unit can move through the phalanx in a way that looks (imo) somewhat nice, you can see that they clump around the tree much easier, and the ressource shuttling is also easier.
However, you can also see some bugs. Pushing isn't as natural as it could be, and units are oriented all wrong, and there's some jerking, and also formations aren't 100% similar to SVN yet.

Does this patch works only for your own units, or also for the enemy units? Because I think you want to be able to block them, e.g. when you try to defend something.

At the moment it's all units. I've thought about this and I'm not sure how to handle enemy units yet.

I actually personally dislike letting units always block enemies, as I find that a little gamey. My feeling was that this might be good to have at some point, like an "anchoring" feature possibly.

Maybe depending on the stance ? I guess that's for the design document to answer. I'd be in favor of enemies blocking because it makes sense

What about that: enemy units give some resistance against pushing, but if they get pushed hard enough they also go away. (Not sure if that is easy to implement)

At the moment I'll focus on sane behaviour regardless of ownership, it's fairly easy to add it in later.

My most problematic case will be gathering units, which need to not move too much when pushed or they might no longer be in range.

From what I know about pushing in SC2, stationary units on a task like attacking (or gathering, although that case does not arise in SC2 because gatherers ignore collisions) do not get pushed at all. There are rules about which units can push which other units.

BTW it would be hella cool if elephants could actually shove aside enemy infantry as they charge through, dealing damage. And the same for cavalry charges. Even better if the cavalry slow down the more infantry they hit.
