Most of the configuration should be +straight forward. If you want to modify the controls, you need to change both +the string passed from pong.tdy as well as the respective function in src/main.rs +(key_down). + +If you want to add more rust functions (for example, to draw text to the screen) +you need to add it like the already existing functions. All functions need a +return type and a return value, even if it is a Type::Void and Value::Nil. (See +e.g. clear for an example.) For a draw_text you probably want to take a +Value::String(s), Value::Float(x), Value::Float(y) and so on. Inside the block +you then write your normal Rusty code. + +After writing your function you also need to link it so you can use it from the +game file. Add it to 'functions' like the other linked functions inside main() +in src/main.rs. + +After linking, the only thing left to do is call it from the game logic. You'll +get a type error if you pass the wrong parameters. Additional parameter +combinations can be set (much like normal function overloading) should you have +the need by adding more "arms" to the extern_function!(). |
