Multi-select help

[izark]

Hello!!
I hope you can help me with this one..

I want to select a group of objects:
I draw a rectangle on the screen with the cursor. All objects touching that rectangle (or inside it) are selected.
Then I can drag and drop the entire group and they are deselected after being dropped.
I can do the drag and drop thing with an object, the problem is groups of objects.

I am not looking for all the code, but a method and useful functions for this. Thank you!!

I think you have to use this [ collision_rectangle(x1,y1,x2,y2,obj,prec,notme); ] in all the objects that you want to select.
Remember to make the rectangle x1,y1,x2,y1 to global variables so then all the objects will find that where the rectangle is drawn.

Yep, collision_rectangle would be ideal. You would use a "with" to have all objects check themselves to see if they fall within the rectangle and if they do then their ID is added to a ds_list or something. You can then parse the ds_list for moving/manipulating those objects.

Thank you for both answers, this is very helpful, I think it is clear now.
I parse then the ds_list and run a similar code to the code for dragging and dropping one
object preserving their relative distance.
