I know how to test for key presses, but for my program I need an action to be performed if a key is pressed and then lifted into the up position. Any Help?

The code works perfectly, but I don't understand select/case/endcase commands. Can someone explain?

Quote: " select oldkeypress
case 57 : print "space key let off of" : endcase
case 30 : print "A key let off of" : endcase
case default : "Some other key let off of" : endcase
endselect"


what happens here is that oldkeypress = the keystate here then this acts like a gosub with if and endifs in them so really it's like say


or something close to this but you's would be fully working the a key in this code doesn't work

Basically it will test if the Variable after "select" matches one of the "case"s and then executes the code in between "case"/"endcase". If no case matches the Variable it will execute Case Default.

Example: (not tested)


Edit: Too Slow

cguy,

Your code is probably not as versatile. It is only setup for one key(returnkey). Also, your setup will only allow for the code needed, to be executed once, and that's it.

Nano brain: You are right about my program not being as versatile as yours, but for what it is trying to accomplish in my program, it is perfect. The only key I'm working with is the returnkey, anyway.

Edit: Actually, you are correct by the second part of your post when you said that It could only be run once. That on second thought will not work.
