Textured Raycaster [Multiple Levels! Door Covers! Jumping!]

[Clouds]

Perhaps I'm being naive, but:
- Won't the floor and ceiling always be "behind" walls? Can't you just draw it without any raycasting, like a background, and draw over it with the walls?
- Wouldn't a mesh object make short work of any necessary perspective (and maybe tiling, if co-ordinates beyond the image dimensions will repeat)?

[Jasoco]

I did, but I'm too lazy to change all of your code to 0.9.0
So much getModes and modes and pixelEffects!

I don't think my version has an getMode or pixel effects in it.

Hhm? Yeah, it had like a choice of resolutions and stuff.

Not to my recollection. My last Wolf engine was static screen size and used no pixel effects.

You cat take a look at this (raycast5 version)
viewtopic.php?f=5&t=35876
I think this version has all the raycasting related stuff moved to a single file, so if You don't mind my chaotic coding it should be useful

This version has vev graphical bugs here and there and of course the florcasting is based on Jasoco's

Well, they need to rotate with you.

I have never dealt with mesh objects, so I don't know. But from my quick glance at the wiki page, I think it wouldn't work.

No clue. Maybe I'm using an old version?

I used some examples from that topic actually.

EDIT: Fixed it! It works now <3 (With the exception of weird jittering)

Second EDIT: Updated main file.

Better than wolfenstein3D.

Now it is.

Either way, a properly written shader could definitely do it. Don't ask me how to code that shader though. lol

it took a while but here it is:

Thanks! I'll try this out to to compare the different methods.

Wouldn't it be easier to pass arguments instead of hard coding the wood and red floor tiles?

Code: Select all

function drawInnerGround()
	love.graphics.setCanvas(groundInner)

	local on = false
	for x = 1, #map[1] do
		for y = 1, #map do
			love.graphics.setColor(255,255,255,255)

			if on then
				love.graphics.draw(img[6], x * 64, y * 64)
				on = not on
			else
				love.graphics.draw(img[7], x * 64, y * 64)
				on = not on
			end
		end
	end
	love.graphics.setCanvas()
end

Yes, but that's just to demonstrate that the floor is not all one tile. Best way is to have 2 or 3 maps. (Walls, floor, ceiling)

Mesh's are terrible at perspective. In that they do not do perspective at all. I find them useless and disappointing personally. I had hoped they'd solve my problem but eh. Whatever. The library I use that was created by xXxMoNkEyMaNxXx (I hate typing that name!) works perfectly and after testing performs exactly the same FPS-wise. If and when I ever do another Raycaster (Probably my next project) I will use it for my floors and ceilings.

whenever I run into a wall I seem to get this error.

Error
