You will need to use these function in a function that runs every frame, i normally hook to CG_DrawNightVisionOverlay and you can find that here 0x42FC8 (as the function is pointless)
This should let u be able to do the type writter effects

You will also need the dvar_t struct in order to use the DvarGetBool function i made, You can find them here You must login or register to view this content.
