Spring RTS Engine

The builder manager of my fledgling AI thinks that in BA, a corlab can assist nearby construction because canAssist is true, and buildDistance is 128.

Yet I know the UI doesn't allow ordering a corlab to assist construction.

Is the corlab able to assist construction? If not, how can I reliably determine that a unit can assist construction without hardcoding mod-specific knowledge?

I am using the Java interface.

BTW, is there some documentation of what exactly the attributes in UnitDef mean? (Most of them don't have any javadoc ...)

canAssist = true on the lab seems like a modmakers mistake, afaik factories can never assist, ony be assisted. (is that the reason why nano towers are units and not buildings?)
I think buildDistance has no effect on factories either.

There are many cases like that, ie a unit might have isTransport = true but ingame it will not be a useable transport unless it has some other tags such as TransportCapacity set.

My Diagnosis?



BAD BABYSITTING MODDING.

Thanks for the links Knorke, they already proved helpful in another matter

I am not sure I understand your distinction between units and buildings though. How does the engine know whether a UnitDef represents a "building" or a "unit"?

I do not know.
Some things might be:
-only buildings have yardmaps?
-some tags like canFly=true will always make it a unit?
TEDClass?

tedclass is not used.

How does spring know? Easy. canMove = true/false,

Building does not have movedef (UnitDef->movedata == NULL). But for example NOTA mod has movable defences: Hatrack (armmllt). It HAS movedef but max velocity is 0.001.

It is just for button in GUI. Do not rely on it. For exmaple it can be used to set rally point for factory.

Yar, I forgot about the obvious fact that a building won't have a movedef.

Does spring round maxvelocity=0, up to 0.1?Another way to do it would be to give the nanotower a massive footprint and 0 crushstrength so that it can't path anywhere.

2 out of 3 ain't half bad.
