Tilemap custom grid brush - two instances in Tile Palette brush selector

[eses]

Hi

I’ve been experimenting with custom Grid Brushes for a while.

So far I’ve understood the brush creation (practical side) works like this:

• Create the code class file
• Add CustomGridBrushAttribute above the class
• Create the brush ScriptableObject Asset file

But for some reason, I have two instances of my custom brush in Tile Palette Brush selection dropdown. However, I can’t find another copy of Asset in my project and I shouldn’t have two similar GridBrush derived classes either with the same attribute.

Have I missed or messed up something in my project? If not, how should I be able to remove the extra copy?

Could you share the flag properties of the CustomGridBrush attribute you have placed?

The main two properties would be:
hideAssetInstances: Hide all asset instances of this brush in the tile palette window.
hideDefaultInstance: Hide the default instance of brush in the tile palette window.

If I am not wrong, one of the instances you have is the asset and the other would be the default instance (The Tile Palette instantiates this for you if you do not need to store custom properties for this brush as an asset). You can disable either type by setting the hide flag for them, which in this case would be the default instance for you?

You are right - It was the default instance.

I probably have dabbled with those flags and then forgotten about those totally!

Thanks!

BTW I did ask another question related to brushes - about using editor keyboard events with Grid Brushes, however I haven’t got any answers to it yet So far my solution was to use OnSceneGUIDelegate of editor and then some of the events seem to work when brush is active:

Tilemap custom brush how to prevent default mouse behavior when painting tiles?

Hi Not sure if I should post this on 2D area or here. Well anyway, move this thread if needed. I was trying to create a scriptable brush and wanted to use modifier keys / right mouse click for extra painting features. I have a typical paint method like this: public override void Paint(GridLayout grid, GameObject brushTarget, Vector3Int cellPos) { // my code here } I can create the default painting behavior and erase things I draw. But I don’t seem to be able find out a way to overr…

Then again, when I created some helper methods, I noticed I could abandon using brushes altogether but it would be nice if somehow it is possible to use more modifier keys / keyboard events with custom brushes.
