im trying to complete a platform tutorial and have ran into this line.
start loop "gravity"ABS(grav("player"))times. everything fine up to the times dont know how to put this expression in.
could you help

Well what Abs() does is return the absolute value of a number (ie: removes the negative if the number is negative). grav("player") means it is referencing an alterable value called "grav" in an active object called "player".

So basically you are starting the loop "gravity" the absolute number of times as the alterable value called "grav" of "player" object.

thanks for your reply. but how do you get the "times" to show up in the event editor. thanks for the detailed explantion now i know what its doing if i could only find out how to enter it.

You are calling a fastloop. The expression editor popup that comes up will first ask you for a loop name, which is "grav" in this example. Then the next one will ask for the number of times to start the loop. This is where the Abs() formula is used for this example.

To do a fastloop, right click in the event editor under Special Conditions-> Fastloops -> Start Loop
