2 problems for you

[The Devourer]

Im working on a mod right now, and i have 2 problems right now, so to save time i thought id ask both!
anyway, to business. The first thing is i wonder how i could make normal units be able to attack buildings, without adding siege weapons or making them technically elephants. ive tried making them fire seige projectiles, but that didnt work.
next i want to add skeletons from another mod, i think i have the tools to do this, but not the knowledge.
Any help on either of thee would be much appreciated.

for the first one - no I don't think so the attack against buildings I think is hard coded.

For the skeletons if their pack contains all the original ones then you could just use their pack instead of the original (gets placed in data/animations)... if you need a mix you have to unpack both packs, re-arrange things and then re-pack.

The unpacking - repacking tool is

Vercingetorix's IDX program, which does have some instructions with it. There are also some topics around here about skeletons if you search for them.

If you've already got that far please be more specific about which bits you don't know how to do.....
