IntGrid lagging when not top layer about ldtk HOT 8 CLOSED

Could you please send me a demo project (including the tilesets) by email (ldtk at deepnight dot net)?

Can confirm that this is an issue with 1.4.1.

I've got a bunch of auto-layers with lots of rules that aren't stopped. On top of that entities layer, some background & foreground.

If "main" layer is in between those auto-layers - painting slows down to a crawl and undo takes seconds to perform on decent rig. Editor just freezes, no extra CPU time taken.

E.g. in this order:

If main layer set first, it works just fine:

Fortunately, I don't need actual layer to be rendered, so as a workaround this is fine.

This should be fixed in 1.5. See #1031 for other rules optimizations

1.5 will have much better perfs overall for rules in large levels.

However, your use-case is a bit extreme, with very large levels + small grid size + many rules. Therefore, there won't be any miracle here: your experience will still be somewhat laggy, even though much more manageable.

What if there was a setting where when on, drawing to intgrid would not apply rules until mouse is released? Drawing to intgrid is just changing a number and you would not need to apply rules every cell change.

I made map maker back in the day where I could edit level of size 30000x30000 and same tilesets from the project i provided without any slowdown. But it was made in GameMaker, so Im guessing LDtk is limited by programing language performance its using?

I could totally add a button to disable rendering "as you draw", but each time you would release mouse button, you will have a lag for re-render.

The issue is not the level size, but the combination of level size + many auto-layer rules.

I found some new culprits and got performances significantly increased with your project file. 👍
