Hi,
ah yes, this is an issue I meant to solve, odd I am sure I did address this at one point...
you have to fill the FsmObject variable with a sprite, otherwise it can't find the type you expect.
so in the variable tab, select your FsmObject of type Sprite, and fill it with a defauls sprite, then the action will work and will understand what resource you want to load.
I'll search my md for the updated action, I am sure I addressed this...
Bye,
Jean
