Anyone know how to make a player do an own built gani?

Bribe them.

yes,
setani yourganiname,;

remember do not include the .gani in the gani name, for example itd be like
setani swim,;

inbetween the comma and the semi-colin put the param number, if no param is being used dont put anything at all.
put setcharprop instead of setani to use it on a showcharacter

Gosh thanks
if i do that does the player do the same as my gani?

and for bomy ganis just say

setchargani bomy_(ganiname in bomy folder),;

so I experimented with this and now on the sever that i am working in I have leveataing bomy danceing bomys farting bomys .ect

hmm, its setcharani, and all bomy ganis start with bomy_ so basically you told him the exact same thing as I did.
