Dynamically animate characters using Liberated Pixel Cup sprites

I haven't had much time for this project lately, but feel free to submit pull requsts for any modifications you would like to contribute. Bonus points to anyone who can synchronize the player's movement with the animation being rendered. :)

This asset allows you to animate a character by layering LPC art at runtime. Given that Unity 5+ doesn't allow for you to change the sprites being used within an Animation at runtime, I had to recreate my own LPC animator to handle the swapping of sprites. The alternative was to generate thousands of prefabs and animations, which would have bloated the project's size beyond anything I would feel is realistic for a 2D game.

I made this asset to gain more knowledge about 2D gaming and Unity. I'm pretty new to Game Development in general so any tips or recommendations would be greatly appreciated! See my contact info at the bottom.

There is not much error handling so the model names will need to match a string from the available model list. This will be improved with drop downs / color pickers in v0.2.

• Demo
• Models Available for the Demo
• YouTube Demonstration

Controls

• WASD for movement
• SPACE - Slash animation
• F - Thrust animation
• E - Shoot animation
• R - Spellcast animation
• Hold LSHIFT - Run faster

OpenGameArt (OGA) is a community for users to share a variety of free/open source art. The Liberated Pixel Cup (LPC) was a contest kickstarted by OGA to create free art that was judged to ensure it was of the appropriate quality and matched a particular art style.

This goes to the Online Universal LPC Spritesheet project and the Universal LPC Spritesheet Unity Importer project, as I would have given up after trying to manually import the beastly number of spreadsheets.

(I will get a page up with pictures here soon..!)

1. Open the project in unity. It will take a bit of time to import the assets as there are ~52k sprites. This will only happen the first time you open the project.
2. Open the demo scene from the root Assets folder.    3. From the Hierarchy window, select the AtlasManager GameObject. You should see an Atlas Manager script component for this GameObject in the Inspector window. If any models are already loaded the first time you go through this process, click on "Unload". Next, click the "Load" button. The first time this may take 15-20 seconds but the next time it should be much faster.  
3. Once all the models have loaded, click on play. All sprites will be packed the first time you play, but the second time this will be skipped.
4. Replace any slot on the left hand side with a value from the Atlas Manager script's Model List attribute. Additionally, you can provide a RGB value on the right hand side to color the model.
5. Click generate

• Mechanism for loading a large number of spritesheets up front
• Create caches to store/lookup independent parts of the LPC character sprites (chest vs body vs helm)
• Create a character state to represent racial configurations and equipement
• Render animations whenever the character state has changed or player input
• Reduce the number of duplicate spritesheets by updating the material color dynamically
• Simple GUI to change the character models at runtime
• Move variables for sprite layers (chest vs body vs helm) into dictionaries to shorten code
• Look for more LPC compliant assets that were not included in the online generator tool
• Create instructions/tutorial in a document or YouTube video.

• Sprite Support: Add more support for sprites such as weapons (knife/mace/short sword) and children.
• Sprite Support: Create appendage character types to handle things like lizard/drake fin, tail, horns, etc.
• Race Creator Tool: Generate new LPC spritesheets (body, eyes) automatically using a color picker!
• Improved GUI: Drop down selectors and color pallettes for the Demo scene.
• New Character Controller: Create non-playable character controller that is integrated with the LPC animator
• Improved Demo Scene: Have NPCs/guards walk the perimiter of the sceen using the LPC animator.
• New GUI Functionality: Spawn a LPC NPC that walks the perimiter using GUI presets/controls

• Repeat the v0.1 Roadmap for LPC compliant Enemies/Animals.

• Network/Multiplayer: Packing and unpacking of "DNA" for network serialization.
• Network/Multiplayer: LAN multiplayer request system
• Network/Multiplayer: Network character controller that can be used during multiplayer
• Network/Multiplayer: Ability to connect clients and see each other.
• Animation: Improve animation speed for all action types (some are too fast..)

• LPC art is dual licensed under GPL3 and CC-BY-SA3.
• All Code/Scripts are available under the MIT license
