How do i make the foxy flash the eyes from FNAF 2?
I've been working on a game, but whenever I try to start a night I get the error "Invalid parameter type at index 1 in function 'MF_GetCSWidth'" I don't really know how to code so I have no idea what this means. Can anybody help?
my fnaf engine version was deleted
