Pick everything in a certain range

Hello everyone,

I need to pick certain objects in range ValueLeft. They need to be set to different frames: black, red, and green for out-of-range, invalid, or valid respectively. However, The object needs to calculate around objects, like this:

Note: blue/red is wall/invalid, white 'p' block is player, black is out-of-range, and green is in range.

As you can see, LOS won't work for this to pick objects, because I need to pick these around corners.

Any help would be appreciated.

you could use isOverlappingAtOffset and put it in a loop so you go through each "cell"

Could someone work through the logic on how to do that? I am having trouble getting it right.

here I'm checking in square grid around the player's nearest owned territory. The size of the grid can change, hence the variable. It's a little complex because I use constants GRID_LEFT etc.. which is just my grid size minus itself. i.e. GRIDSIZE = 32, GRID_LEFT = -32, GRID_RIGHT = 64 etc....

Just to make your code a little clearer, what size is the system_select object? Where is it located?

Thank you for your help!

the system_select object is the exact size of the grid. So this is when the selection is on a particular grid piece, it then checks all the other grid pieces adjacent, so 3x3 around a center piece. Then if the range is 2, it goes out "1 further" 5x5 etc...

so in your case I think you just want to test every grid piece in your layout. But this is how I use isOverlappingAtOffset.

It's used like an IF CONDITION. "If it were here, would it be overlapping object X?" is the logic behind it.
