Hey everyone,
Well recently I decided to make a matrix editor in dbpro (just as a way of learning more about the matrix commands). So far I've been successful in making a mouse cursor object that you can move along the matrix, and raise/lower single matrix points by click near the point you want to edit. Now my problem is that I want to make it so that I can move more than one point at a time. Looking around at the other matrix editors I found that Magic World has a really nice way of doing it (ie: making a circle and checking to see whether or not the co-ordinates of the points on the matrix fall inside the radius of the circle).

My problem is that the only way I can think of doing this is by using a FOR / NEXT loop and going through every point of a matrix to see if it falls inside the radius. While this works fine, on a larger matrix (with more points) it would definitely start to slow down. So here is the crux of the issue, is there a way of localising (or refining) the loop in any way so that it doesn't have to go through all the matrix points?

I hope I've explained the problem with enough detail, and thanks in advance to any advice posted (it will be much appreciated).

Cheer,
Sina.

if the gap between each point is for instance 100, and the radius is 500 you'd only need to check the points 5 tiles away.

Hehe, hadn't thought about it that way. Guess it could work thanks .

Hmm, just out of interest (and before this post dies), does anyone else have any suggestions?

While ReD_eye's suggestion would probably work quite well, are there other ways of doing?

Thanks again,
Sina.
