PHP код:

#define HOLDING(%0) \
    ((newkeys & (%0)) == (%0))
    
if(HOLDING(KEY_HANDBRAKE))
{
    //Remove the bandana
}
else
{
    //create the bandana again
} 


You can remove the bandana if you holding the right mouse button and create it again if you don't press it.
I don't know if you have to use HOLDING or PRESSED.
