linc_sdl's Issues

Trying it out for the first time.

So i've decided to finally give it a try but unfortunately run into some problems.

First the example is missing imports for Window, Renderer then it is missing a final return for the update method and Haxe will complain. After finally being able to compile it with -D HXCPP_M64 and running hxcpp on the generated Build files it gets compiled into an application but this application autocloses right away upon being run.

Any ideas?

Compilation fails under OSX Yosemite

I tried to compile your example on my mac but I get a bunch of "duplicate symbol" errors.
Full log: https://gist.github.com/icek/951790c5ec9f489b56c2

Implement #if cppia #end to generate Haxe wrapper functions around native calls?

Implementing a switch to offer wrapped calls would mean compatibility with Cppia hosts and scripts. Is this too out of scope for this library, and a wrapper library implemented separately?

Can't compile

I can't seem to get the test to compile. Getting the same error when compiling on Mac and Windows.

Error: ./src/Test.cpp:1571:20: error: no member named 'sym' in 'cpp::Struct<SDL_Keysym, cpp::DefaultStructHandler>'; did you mean to use '->' instead of '.'?
int tmp10 = tmp9.sym; HX_STACK_VAR(tmp10,"tmp10");

Windows builds broken with cl.exe

These lines

#ifndef HXCPP_H
#include <hxcpp.h>
#endif

are not valid on windows with cl.exe. Anything before the include statement for a precompiled header is ignored, making the #endif a syntax error

Android target error: SDL could not create window.

I tried compiling linc_nanovg test/snow example on android target: I am getting this error

E/Exception: error(runtime / sdl / failed to create platform window, unable to recover / `Could not initialize OpenGL / GLES library`)

The error seems to be coming from SDL, so I am hoping you might be able to help.

linc_sdl : SDL.Keycode: Pattern matching havoc

Hi,

Since switch does no pattern match variables but only constants (static inline), the whole Keycode class is a potential disaster (at least with recent haxe versions).

for example : key_1 is static var and thus the pattern matcher will use every work key_1 as switch traps and all the code in the switch is a potential switch trap.

I suggest obliterating the code (asap) and replacing the old implementation switch with an Int Map matching keycodes and scancodes.

import sdl.SDL;
import sdl.Window;
import sdl.Renderer;

class Main {

    static var state : { window:Window, renderer:Renderer };

        //Haxe entry point
    static function main() {

        SDL.init(SDL_INIT_VIDEO | SDL_INIT_EVENTS);
        state = SDL.createWindowAndRenderer(320, 320, SDL_WINDOW_RESIZABLE);
        update();

    }

    static function update() {
        while(SDL.hasAnEvent()) {

            var e = SDL.pollEvent();
            if(e.type == SDL_QUIT) return false;

            SDL.setRenderDrawColor(state.renderer, 255,255,255,255);
            SDL.renderClear(state.renderer);
            SDL.renderPresent(state.renderer);
            SDL.delay(4);

        }

        return true;
    }

}

I get the following error upon compilation:

Any assistance would be appreciated.

SDL_Image support

So I was using this (really nice) library to port my code from C++ to Haxe but I see that there's no SDL_image support.
I need to use PNG and JPG images, but the SDL library only accepts BMPs.

I wanted to implement it myself, but I the library isn't on native-toolkit's GitHub.

Any ideas?

SDLRect Compile Error

So I am trying to us SDL.blitSurface

this is my function

public function apply_surface(?x:Int = null, ?y:Int = null, source:Surface, destination:Surface, clip:SDLRect){
        //Holds offsets
        var shift:SDLRect = {y:0, x:0, w:0, h:0};

        //Get offsets
        shift.x = offSetX;
        shift.y = offSetY;

        //Blit
        SDL.blitSurface(source, clip, destination, shift);

    }

I am getting this error

error C2664: 'int SDL_UpperBlit(SDL_Surface *,const SDL_Rect *,SDL_Surface *,SDL_Rect *)': cannot convert argument 2 from 'Dynamic' to 'const SDL_Rect *'
