CRITICAL: Import Settings for Tiles
Get this wrong and everything breaks
▶
⚠ You MUST configure these settings before using any Kenney tiles!
Kenney tiles are 70×70 pixels each. Unity defaults to 100 Pixels Per Unit, which will make your tiles the wrong size and leave gaps everywhere.

Required settings for EVERY tile import:
• Pixels Per Unit: 70 — matches Kenney's 70×70 tile size
• Filter Mode: Point (no filter) — keeps pixel art crisp with no blurring
• Sprite Mode: Single — each tile image is one complete tile

Step-by-Step Import Setup

  1. Select ALL tile images you imported (Shift+click to multi-select in Project window)
  2. In the Inspector → set Pixels Per Unit: 70
  3. Set Filter Mode: Point (no filter)
  4. Click Apply at the bottom of the Inspector
⚠ Tiles look too big or too small? The Pixels Per Unit is wrong. 70 is the magic number for Kenney tiles! If you see gaps between tiles or they overlap, double-check this setting on every tile sprite.

💡 Build pattern: Use grassLeft on the left end, repeat grassMid across the middle, and grassRight on the right end. Fill below with grassCenter. This is the same pattern for every world theme!

Other World Themes
Same naming pattern, different visual styles
▶
✅ Every theme follows the SAME naming pattern! Just swap the prefix. If you know the grass tiles, you know them all: [theme]Mid, [theme]Left, [theme]Right, [theme]Half, [theme]Center, [theme]CliffLeft/Right, [theme]HillLeft/Right, [theme]LedgeLeft/Right.

💡 Mix and match! You can combine tiles from different themes in the same level. Use grass for the surface and stone for underground caves. The tiles are all the same 70×70 size so they fit together perfectly.

Backgrounds for Your Tilemap Level
Sky and scenery behind your tiles
▶
FileLocationDescription
bg.pngBase pack/Default sky
bg_castle.pngBase pack/Castle sky

bg_desert.pngMushroom expansion/Backgrounds/Desert
bg_castle.pngMushroom expansion/Backgrounds/Dark castle
bg_shroom.pngMushroom expansion/Backgrounds/Mushroom world
💡 Background setup: Drag the background image into your Scene, set its Order in Layer to -10 (or any negative number) so it renders behind everything else. Scale it to fill your camera view.

Tile Palette Setup Steps
Create a palette and start painting your level
▶

Creating Your Tile Palette

  1. Go to Window → 2D → Tile Palette
  2. Click Create New Palette → name it "GrassTiles" (or your theme name)
  3. Grid: Rectangle, Cell Size: Automatic
  4. Create an Assets/Palettes/ folder and an Assets/TileAssets/ folder
  5. Drag all your tile PNGs into the Tile Palette window
  6. Save tile assets to the TileAssets/ folder when prompted
  7. Start painting!

Painting Tool Shortcuts

KeyToolWhat It Does
BPaint BrushPlace one tile at a time
UBox FillDrag to fill a rectangle with tiles
DEraserRemove tiles
IEyedropperPick an existing tile from the scene
GFlood FillFill an entire area with one tile
✅ Pro workflow: Select a tile in the palette, press B to paint, hold Shift to draw straight lines. Use U (Box Fill) to quickly fill large underground areas with grassCenter or dirtCenter tiles.

Collision Setup
Make your tiles solid so the player can walk on them
▶

Adding Collision to Your Tilemap

  1. Select the Ground Tilemap in the Hierarchy
  2. Add Component → Tilemap Collider 2D
  3. Add Component → Composite Collider 2D (merges individual tile colliders into one smooth surface)
  4. A Rigidbody 2D is auto-added — set Body Type: Static
  5. On the Tilemap Collider 2D component, check "Used By Composite"
  6. Set the Tag to "Ground"
⚠ Do NOT add colliders to background tilemaps! Only the Ground tilemap needs collision. If you add colliders to decorative or background tiles, your player will get stuck on invisible walls.
💡 Why Composite Collider? Without it, every single tile has its own tiny box collider. Your player can catch on the edges between tiles and stutter. The Composite Collider merges them into one smooth shape.
