Mod requests (orders).

How do I set up animations for abilities?

Find the CreatureVisual line in the file where you edited the parameters and remember the path. Open the map editor (yes, I will keep repeating that it's easier to do these small things in the map editor!) in advanced mode, with everything closed (Resource => Close MOD is grayed out).
Now, find the Creature table, then navigate through the folder structure to the creature files, which is the same as indicated by vasik. Double-click to open the creature files and go to the properties (if the properties window is not visible, go to View => Select Properties Window).

All the parameters will be conveniently "arranged" there. Find CreatureVisual => ... => AnimCharacter => ... => ArenaAnimSet => In the properties of AnimSet, there will be a list of existing animations. Expand it completely. In each element, there will be a line called name with a code and understandable name for the animation, and below it – BasicSkelAnim, a link to the animation itself.

To swap the attack animation with the movement animation, simply select the BasicSkelAnim from move under the attack00 line and vice versa.

To create a new one (for example, if there is no range/specability/stir00/cast), create it, enter the corresponding exact name in the name field, and in BasicSkelAnim, select any of the existing animations for the unit.

I hope I explained it well; sorry in advance for any inaccuracies 🙂
