Mobile idle farm game that we're developing with a small team for UK-based investor. The game is built with Unity using an in-house IoC and DI solution called PostMVC.

My responsibilities on the project are:

• General gameplay and graphics programming
• Rendering & code optimization

During development I've faced and overcame the following challenges:

• Created an algorithm to select appropriate tile image from the collection based on the shape of the generated map:

Original biome data (blocks of 128x128)

Atlas (distorted) of tiles used to connect the edges of the biomes

Tiles from the atlas are selected and placed procedurally

• Greatly reduced tilemap draw calls by correctly configuring sprites and atlases and spacing out the sprites so different atlases don't overlap on Z-axis (built-in tilemap batching was not available because we had overlapping sprites):

3D placement of the tiles

Only 3 draw calls ared needed to render it

• Made a touch scrolling and scrolling inertia implementation from the scratch

• Wrote a fast and efficient view for tile overlays containing images and text that covers the entire game field with over 1000 managed instances:

• Cloud sprite placement & shadow shader:
