Reading Controllers Reading controllers on the GameTank requires to add #include “input.h” as an include file. The API is pretty straighforward: update_inputs(); if (player1_buttons & INPUT_MASK_LEFT) { ... } else if (player1_buttons & INPUT_MASK_RIGHT) { ... } if (player1_buttons & INPUT_MASK_UP) { ... } else if (player1_buttons & INPUT_MASK_DOWN) { ... } // players_old_buttons is used to make sure users press and release the button if (player1_buttons & ~player1_old_buttons & INPUT_MA…

GameTank SDK The C SDK provides a collection of libraries and tools to support making GameTank games entirely in C! It's available on GitHub. You can start a git repository using the SDK as a template and customize it as much or as little as you want. The SDK also makes it easy to bring artwork and music into your project, as well as update any asset changes using the provided conversion scripts and generated header files.

Debugging your Program The GameTank emulator contains a few tools to debug your program: * The VRAM Viewer allows to check what is actually loaded in VRAM * The Memory Browser allows to look at the RAM. Its Variables tab allows to see the value of any global variable defined in C

Getting started with the GameTank C SDK To start a new project you can use the template feature on github to create a new repository based on a snapshot of gametank_sdk. Along with the SDK itself you'll need to install some other tools: cc65 cc65 is an open source toolchain for cross-compiling C to 6502-based platforms. It includes a C compiler, an assembler, and a linker. It supports multiple variants of the 6502, including the 65C02 and the W65C02S used by the GameTank.

Graphics on the GameTank In most systems, a sprite is a graphical resource of limited size that can be moved across the screen without modifying the playfield. Not so on the GameTank. A “sprite” here can have any size (up to 127×127 pixels) but cannot be moved. It

Importing and Playing Music Just like for graphical assets, sound assets need to be stored in the assets// directory and require to run make import to generate the necessary files. Contrary to the graphical assets they do not need to be loaded explicitly.

Importing and Drawing Sprites The SDK makes it easy to bring images into your game after you've exported them, particularly from Aseprite. This page will go into a bit more detail on how to incorporate the image files into your project and then how to load and draw them in your code.
