affecting a large group of duplicate objects seperately

I have a large grid of duplicate objects.

I'd like to have each one have seperate collision.

right now if I create a large grid of the same object, and then apply

if mouse is over object then change opacity to 50

if mouse is not over object then change opacity to 100

each object is changed as I mouse over each one, but I have to move the mouse away from the entire group for them to change back to 100 opacity, i'd like each object to change individually..

can anyone point me in the most sensible direction to achieve this?

thanks as always..

If objects are too close together, then the condition remains true while mouse moves over objects, as it doesn't actually leave the object type yet.

But here is an unique property of each object instance: Unique ID - UID. See the code:

+MouseKeyboard: Mouse is over Sprite 

There's an even simpler way.

+ Always

-> Set object opacity to 100

+ Mouse is over Sprite

-> Set object opacity to 50

Events are read in top to bottom order, so they all have 100 opacity, except for the one under the mouse. "Mouse not over object" won't be true and won't run until the mouse isn't over any of the object, hence the problem.

thanks, that seems to only affect one at a time though, if a larger object that covers more than one object overlaps them, only one is affected..

my apologies if I came across as too specific..

Sprite is over sprite

set opacity-

Sprite is not over sprite

set opacity+

using a sprite as pointer....

I don't understand. Do you have a .cap?

Yep, this would work pretty good. Just make a tiny sprite and always set it to mousex, mousey.

sorry ash, that works wonderfully, I was responding to the previous poster..

I think we may have posted our responses around the same moment

Thankyou all

I learned a lesson, too!
