Foreground Elements

[Otukuoi]

Would it be possible to have foreground elements (e.g. the structures in Star Light Zone) using the background functions? If not, would it be better to just make it from scratch?

You mean those pillars that scroll past the foreground? Technically background functions would work, but the framework draws the background elements at maximum depth (ENGINE_RENDERER_DRAW_PRIORITY, which is 16000)

You could try to change the depth mid-draw and then revert it back to the initial value, but I never really tried it so can't say for sure. It is better to make them from scratch, I guess I can even share the code from my S1R project:

var Offset = 112 + (global.Width - 320) / 2;
	
var PosX = Camera.ViewX - (Camera.ViewX * 2 + Offset) mod 512 + 512;
var PosY = Camera.ViewY -  Camera.ViewY * 2 mod 64;

for (var i = global.Width div 480; i > -1; i--)
{
      draw_sprite(sprite_index, 0, PosX + 512 * i, PosY);
}

Obviously ctrl+C ctrl+V won't work here due to it using different variables (the code is from iteration of OF1), but the idea is here

In that case, would I just rewrite the code to fit with the new engine or would the entire concept just not work in OF2?

[TrianglyRU]

The former. You just need to adapt the code to work with OF1
