I’m not certain exactly what the error you are having. Is it not compiling? Is it leaving white boxes?
Aside from that… not sure. if it compiles and runs you might put up a screenshot of what it’s doing.
slicedpan wrote:> Hi, i’m writing what is possibly the beginning of some sort of 2d platformer with physics. I’m struggling with this one particular section of my rendering code. I have been reading some tutorials and most of the following code works. I have some simple polys rendering in world coordinates, then an overlay that renders on top using the same coords as the screen. however am trying to implement some textures and i just can’t seem to get them to work. I’m sure i’ve just done something really stupid, anyway heres the code:
Code:
void CMyEngine::Render( SDL_Surface* pDestSurface )
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT) ;glPushMatrix(); gluOrtho2D(campos_x, (SCRWIDTH/SCALE) + campos_x, campos_y, (SCRHEIGHT / SCALE) + campos_y); prim_cont->Draw(); glPopMatrix(); // this part renders the physics object using solid color polys, this works glPushMatrix(); gluOrtho2D(0,SCRWIDTH,0,SCRHEIGHT); ol_cont->Draw(); glPopMatrix(); // this part renders the overlay, this works too glEnable(GL_TEXTURE_2D); //this code should hopefully draw a textured rectangle on the screen glEnable(GL_BLEND); glColor4d(1, 1, 1, 0.75); glPushMatrix(); gluOrtho2D(0,SCRWIDTH,0,SCRHEIGHT); glBindTexture(GL_TEXTURE_2D, G.tex); // G.tex holds the texture number, i've checked and it's not equal to zero glBegin(GL_QUADS); glTexCoord2i(0,0);glVertex2d(0.0,0.0); glTexCoord2i(0,1);glVertex2d(0.0,258.0); glTexCoord2i(1,1);glVertex2d(387.0,258.0); glTexCoord2i(1,0);glVertex2d(387.0,0.0); glEnd(); glPopMatrix(); glDisable(GL_TEXTURE_2D); glDisable(GL_BLEND); SDL_GL_SwapBuffers();}
The code that loads the texture is taken from here (http://anomtech.uuuq.com/Index.php?page=glTextures), i’ve checked that guys source and it compiles and shows the same texture correctly. any help would be much appreciated thanks.
