Keyboard interaction

This part of Ikarus implements function that make interaction with keyboard possible.

Info

Keyboard interaction is also implemented with gameKeyEvents.d

Initialization

The best way to initialize all Ikarus functions is to call MEM_InitAll() in the Init_Global() initialization function.

Warning

If you want to use Ikarus in Gothic 1, it is best to define your own Init_Global() function and call it from every world initialization function.

1
MEM_InitAll();

Implementation

Ikarus.d on GitHub
