C++ (Cpp) checkTexture Examples

Example #1

File: register_graphics.cpp Project: Murii/simple

int register_graphics::loadTexture(lua_State *L)
{
        texture2D* tex = checkTexture(L, 1);
        luaL_checkstring(L, 2);
        const char* path = lua_tostring(L, 2);

        tex->create(path);
        return 1;
}

Example #2

File: register_graphics.cpp Project: Murii/simple

int register_graphics::deleteTexture(lua_State *L)
{
        texture2D* f = checkTexture(L, 1);
        if (f != NULL){
                SAFE_DELETE(f);
        }else{
                LOG("can not delete texture because it is null!");
                return 0;
        }
        return 1;
}
