ok, this is upsetting me. my keyhandler should be detecting mousepresses, and it is, but only if i hold it down for a half second. The annoying thing is that if i tell my program to print a line at the code that detects the press, IT WILL PRINT, yet apparently will only print and will not set the value of mouseclicked to true unless i hold it down. is this a bug? this has to be a bug? how do i fix this? if i run this, it outputs the line "THIS IS DETECTING!", so logically mouseclicked should be set to true, but it is not. This is weires and contrary to the way programs are supposed to work. help would be very appreciated.
