Hey @Schneekuchen!
- First of all, you should plug the mesh into the skeletal mesh component pin of the Play Montage node like this:
-
If the issue still persists though, could you clarify if your custom event get triggered? (You can check by clicking on the node and hitting F9 to toggle a breakpoint, the game should be paused the next time you playtest if it indeed gets triggered.)
-
Next, does that Print String node connected to the True pin of your Branch node print to the screen, meaning the conditions are actually met? Due to the characters’ capsule components, they can only get so close to each other. Given that they can’t overlap each other, of course. For example, if each have a capsule radius of 30, the minimum distance between them would be greater than 60.
-
About your alternative approach, if the On Component Begin Overlap event of your sphere collision didn’t even get triggered, make sure to have the Generate Overlap Events property of both of the characters’ capsule components is enabled.
-
However if the issue isn’t about the points above, make sure to have the default slot plugged into the main output pose of your anim graph like this:
Hope these help!
