I can't use the Brush in the tilemap

Sooo, I want to create a simple tilemap, I have my sprites 16x16, not needed to be sliced, I created a grid, a 2D rectangular tilemap with a renderer being activated and after creating my pallete and dragging my sprites in it, I want to use the brush but it paints nothing

I’m trying to paint but it doesn’t work, any tips?

1. Ensure Your Tilemap Is Active

  • Check if the Tilemap GameObject is active in the hierarchy. If it’s inactive, you won’t be able to paint on it.

2. Tilemap Component Setup

  • Verify that your Tilemap Renderer and Tilemap components are correctly added to the tilemap GameObject. The Tilemap Renderer is what visualizes the tiles.

3. Grid and Tilemap Alignment

  • Ensure your Tilemap is a child of the Grid GameObject.
  • Check the size and alignment of the Grid component. It should match the 16x16 size of your sprites.

4. Palette Issues

  • Confirm that you created the palette correctly:
    • Create a new palette: Go to Window > 2D > Tile Palette, then create a new palette with a matching grid size (16x16 in your case).
    • Drag the sprites into the palette and check that they were converted into Tiles. If they’re not visible in the palette, something might have gone wrong during this step.
  • Make sure you selected the correct palette from the dropdown menu in the Tile Palette window.

5. Check Sorting Layers

  • Ensure the Sorting Layer and Order in Layer of your Tilemap Renderer are set correctly. If it’s on the wrong layer or below other objects, the tiles might be “invisible.”

6. Select the Correct Brush

  • Double-check the Brush Tool you’re using in the Tile Palette window:
    • Ensure you’re using the Default Brush unless you have specific requirements.
    • Click on a tile in the palette to select it, then try painting on the tilemap.

7. Inspect the Scene View

  • Make sure you are in the Scene View and the tilemap is in a visible area.
  • Zoom in on the tilemap to ensure your tiles aren’t being painted off-screen.

8. Colliders and Layers

  • If you’ve added a Tilemap Collider or other components, they might interfere with editing. Temporarily disable those components and try painting again.

9. Tiles Missing a Sprite?

  • If the tiles in your palette don’t display properly, they might not have been assigned a sprite during creation. Right-click on the tile in your Assets folder and check the Inspector to ensure the correct sprite is assigned.

10. Tilemap and Brush Settings

  • Check the Inspector for the active Tilemap. Ensure there are no settings (like custom materials or layer masks) that prevent rendering.
  • In the Tile Palette, check the brush settings for the correct grid snapping and alignment.

11. Debugging Layers and Cameras

  • If you’re using a Camera, ensure the tilemap is within the camera’s Clipping Planes and that the camera can render the Sorting Layer the tilemap is on.

12. Console Errors

  • Check the Console for any errors or warnings. Sometimes Unity will indicate what went wrong during the tilemap setup.
