So when i test my game i always get this weird log error and what does it even mean:

when i press it it leads me to a blank construction script in the scar h

it seems like searching cast to fps controller in scar h now this is the cast

any ideas how to solved it?

in your second picture you are casting to FPSController, but the input pin for that node has nothing, that mean that you are casting nothing to a FPSController.

Which part of the cast node is the input one?

you need to put something in the part of the node that says “object”

i see thanks
