Feedback Better sprite slicing. Grid based pivots.

I want to have sprites that have pivots in the center of the grid cells, but the sprites themselves to be trimmed.

Sprites like this:


But then the pivots are relative to the bounds, and this doesn't work with animation well. So I want pivots to be relative to the grid. As if I sliced by grid cell.

 

Do you want them to be trimmed so there's less overdraw? If so, then if you ensure that on the sprite's texture you have it set to Tight (instead of Full Rect) then it will automatically essentially trim it. The rect will remain large but there won't be empty overdraw (edit: With Tight setting, distinction is between sprite.textureRect, which is small, vs sprite.rect which remains large). It's also possible to provide a Custom Outline to fine-tune it within the Sprite Editor.

If on the other hand you have some very particular need, then you could use the scripting API for the Texture Importer and process your textures sprite metadata to achieve the effect you want. This would probably mean using the trim tool by hand, then processing it to position the pivots as if they are on a grid.

 

Thank you for the information. I didn't know that there are two rect variables. I will use tight for the texture rect. Yes processing option would be on the table, but I just need less overdraw.
