Creating 2d games in Unity

Learn how to customize a Unity ScriptableWizard to build texture atlases by selecting textures, naming the atlas, and implementing onWizardCreate to generate the atlas texture.

Configure textures for atlas packing by adjusting Unity import settings, set power-of-two handling, read/write, wrap mode to clamp, and filter mode to point, then apply and reimport.

Automate texture import settings for Unity atlases by applying a configure for atlas function to every texture in the textures array. Generate the atlas texture after configuring all textures.

Generate an atlas texture by padding and packing multiple textures in Unity, save as PNG, import back into Unity, and assemble four textures into a single atlas.

Learn to record atlas UV data by creating an atlas data component that stores the atlas texture, subtexture names, and UV rectangles, attached to an invisible game object.

Generate the final atlas texture by creating an atlas object, adding atlas data, and populating names, uvs, and texture references.

Learn to edit UVs in Unity by mapping atlas textures to quads using a custom atlas sprite editor and switch to unlit transparent materials.

Set up a pixel-perfect shooting gallery in Unity using quad atlas textures, with enemy and background objects, a foreground cursor, and game over visuals, ready for upcoming coding.

Create a Unity game manager component to track game state and control the cursor image by updating its transform each frame, so the on-screen cursor follows the mouse.

Create a Unity 2d game manager to track hits, enforce a 60 second time limit, and show win or lose images based on a hit threshold.

Implement a coroutine to wait the time limit, remove enemies, and display win or lose based on hits versus the limit, through the game manager.

Implement 2d Unity enemies that slide between points at constant speed and notify the game manager on hits. Create an enemy component with a hit method that increments the counter.

See how the enemy moves toward destinations, adjusts speed, and notifies the game manager on hits, while clicks only affect enemies with the correct box collider.
