💅 image_set_txcos(3) ✨

okay bestie, you're reading the image_set_txcos(3) page from the Arcan Lua API, and it's literally about overriding the default texture coordinates for an object. no cap. 🎀

🌸 NAME 🌸

image_set_txcos — Override the default texture coordinates for an object.

✨ SYNOPSIS ✨

here's the signature, bestie:

nil
image_set_txcos( vid, txco_t )

🦋 DESCRIPTION 🦋

okay so here's the tea ☕: some specific effects and tricks — or manually maintaining spritesheets or similar image packing options — require that texture coordinates are skewed. you can pull that off either in the vertex shader stage or by statically overriding the default. that's the whole vibe. 💫

🔥 EXAMPLE 🔥

this example is lowkey iconic, no notes:

       function image_set_txcos0()
             a = load_image("test.png");
             show_image(a);
             image_set_txcos(a, {0.5, 0.5, 1.0, 0.5, 1.0, 1.0, 1.0, 0.5});
       end
