Just pass an identity transform to al_use_transform before drawing the text: //.. ALLEGRO_TRANSFORM identity; al_identity_transform(&identity); al_use_transform(identity); al_draw_textf(numArrow, al_map_rgb(252,209, 22), 10, 10, 0, "Arrows: %i", arrow.arrowCount); al_draw_textf(numCoin, al_map_rgb(252, 209, 22), 10, 50, 0, "Coins: %i", coinCount); // ..
