weskinner / crystal-sdl2 Goto Github PK

Hi,

Please add a working sample for how to use crystal and SDL2.

crystal-tetris does not work with the latest version of crystal/shards/SDL2. (and crystal-tetris does not have an issue tracker).

Projectfile was never read by crystal deps. It attempted to read shard.yml, so I created this one that may or may not be correct:

name: tetris
version: 0.1.0

dependencies:
  sdl2:
    github: weskinner/crystal-sdl2

When compiling, there were several errors.

Output when building:

crystal tetris.cr 
Error in ./tetris.cr:1: while requiring "./src/main.cr"

require "./src/main.cr"
^

in ./src/main.cr:3: while requiring "./graphics"

require "./graphics"
^

Syntax error in ./src/graphics.cr:85: expecting token ')', not 'as'

      LibSDL2_GFX.box_color(@render as Void*, x_tl, y_tl, x_br, y_br, color);
                                    ^

Tested with crystal 0.19.4 (2016-10-07), shards 0.6.3 (2016-09-06), sdl 2.0.4 on 64-bit Arch Linux.

Cheers!

I've been playing around with crystal-sdl2 and asked myself, why structs? I can't see them a good fit and with classes is possible to call to free inside finalize (finalize won't work otherwise).
