EVENT/CUSTOM HANDLERS

A custom handler is useful when you want to write a series of commands and checks to be executed several times during the course of a movie.

In the example below the “on checkhits” event is placed in a global movie script—it can be placed just below the on startmovie handler.

Used in movie “breakout_sample.dir” in Files for Courses>Tiffany Holmes>Interactive_Multimedia>Class 6 on the ATS File Server X.

on checkhits

global ghitlist

--this global records the channels of the sprites hit

if count(ghitlist) = 10 then

--reset other globals and move to next marker

gx=1

gy=1

hitlist=[]

go next

end if

end
