I think the reason for it not translating when I hit ‘a’ is because this function:
void renderTile(void)

{
for (int w = 0; w < 50; w++)
{
if (Map1[h][w] == 0)
{
glBindTexture( GL_TEXTURE_2D, tex0);
}
else if (Map1[h][w] == 1)
{
glBindTexture( GL_TEXTURE_2D, tex1);
}
glPushMatrix();
glTranslatef(h, -w, 0);
glBegin (GL_QUADS);
glTexCoord2d(0.0, 0.0);
glVertex3f(0.0, 0.0, 0.0);
glTexCoord2d(1.0, 0.0);
glVertex3f(1.0, 0.0, 0.0);
glTexCoord2d(1.0, 1.0);
glVertex3f(1.0, 1.0, 0.0);
glTexCoord2d(0.0, 1.0);
glVertex3f(0.0, 1.0, 0.0);
glEnd();
glPopMatrix();
}
}
}
is constantly redrawing at set coordinates with
glTranslatef(h, -w, 0);
So, does anyone know how I could make it so that I could translate the board?
