#TPCodeaExamples

Example projects for Codea TexturePacker exporters (https://github.com/apendley/TPCodea), and home of the SpriteBatch class for batch-rendering sprites in Codea using TexturePacker-generated sprite sheets.

##Importing example sprite sheet texture into Codea ###Import via copy/paste

1. Open https://github.com/apendley/TPCodeaExamples/blob/master/assets/SmallWorldSprites%402x.png in Mobile Safari, and copy the image to the clipboard
2. Import the copied image into Codea. Make sure to name it "SmallWorldSprites" (without the @2x suffix), and make sure the Retina option is selected, so Codea will create the non-retina version.
3. Open the TPCodeaTabExample and/or TPCodeaChunkExample project in Codea and run it!

###Import via photo album

1. Save the texture at https://github.com/apendley/TPCodeaExamples/blob/master/assets/SmallWorldSprites%402x.png into your photo album
2. Follow steps 2 and 3 from "Import via copy/paste" above

###Import via Dropbox ####Step 1: Import the texture

1. Copy the SmallWorldSprites@2x.png and SmallWorldSprites.png textures from the assets folder into the Apps/Codea folder in your Dropbox.
2. In Codea, sync your Dropbox sprite pack

####Step 2: Install and modify the project(s) #####Modifying TPExampleCodeaTab

1. Install the TPCodeaTabExample project into the Codea app
2. In the setup() function in the Main tab, change batch = SpriteBatch(tp["SmallWorldSprites"]) to batch = SpriteBatch(tp["SmallWorldSprites"], "Dropbox")
3. Run the project

#####Modifying TPCodeaExampleChunk

1. Install the TPCodeaChunkExample project into the Codea app and open it
2. In the createBatchRenderer() function in the Main tab, change batch = SpriteBatch(object) to batch = SpriteBatch(object, "Dropbox")
3. Run the project

On the first run, the sprite sheet data will be downloaded from assets/chunk/SmallWorldSprites.lua in this repo. On subsequent runs, the sprite sheet data will be loaded from your project's data instead of being downloaded.

##Notes:

• I've added the Small World assets and the TexturePacker file for reference so you can see how the sprite sheet is assembled, and so you can see the AutoSD options used to create a non-retina version of your sprite sheet texture.
• When creating sprite sheets for your own project, you only need to have TexturePacker generate the non-retina version (using the AutoSD feature) if you plan on using Dropbox to import your sprite sheet texure into Codea. If you import using the copy/paste or photo album methods, Codea can automatically generate the non-retina version when you import the texture.
