[quote="Madster":3u2dq9ry]you can use System-Compare, that one allows you to compare anything. The objects that satisfy the comparison will be picked.[/quote:3u2dq9ry]
Just to clarify (in case people find this thread via search in future etc): system compare deliberately does not do any picking at all. However, you can simulate the effect of picking by putting a 'for each' above it. Other comparison conditions, eg. in the sprite object, pick normally.
[quote="Davioware":3u2dq9ry]be careful with overlapping at offset, it's hard on the cpu.[/quote:3u2dq9ry]
No more so than ordinary overlaps, which don't usually bottleneck performance.
