Selecting objects

How to create something to select objects like that one in the picture ( when i'm mooving the mouse, square gets bigger and bigger like in the OS (operating system).).

Basically you can draw a rectangle on a canvas. When you click, store the mouse position, and set a variable. On draw, check the variable to see if you are clicking, and if so, (re)draw a rectangle from the click position to the current mouse position. On mouse button up, turn off the variable, and erase the rectangle. Then a good way is to loop through every object that can be selected, and if it's inside that rectangle, select it.

I was experimenting with this....it would be nice if we could just call a collision from the rectangle itself.....
I'm always trying to use collide to determine events but there's so many instances where it doesn't work right.

In a puzzle game, i got all the blocks to fall and stop evenly with an array. Problem is...i couldn't use collide...cause they were perfectly stacked and there were no collisions to occur....

Here it is! Selecting multiple objects in Ge....Just like you do in windows!

They don't deselect when you change the box size, just draw another one!

I also found a way to fill the box in with a transparent color, and it worked great, at least....except for using 95% of a 3.6ghz cpu. So you'll have to settle for the empty box
