I tried to learn how to make a raycaster earlier, but then remembered that I can neither code nor do proper maths. Quite depressing. I do like the little hand bob by the way. For a second I actually thought the whole screen was moving until I remembered it was a raycaster.

It also has a simple day/night system now.

I get errors when I try your games

NS_ERROR_NOT_AVAILABLE

Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIDOMCanvasRenderingContext2D.drawImag

I'm on FF 3.6.12

Upgrade your copy of FireFox.

To clarify further, the issue older versions of FF did not keep to the correct spec. This meant stuff I did, which was valid, can cause FF 3.6 to crash. FF 4 and 5 are far more compliant to the spec.

This raycaster reminds me of that old win95 maze screensaver that I used to absolutely love. Didn't know it was raycasting back then, mainly because I didn't know what raycasting was. ^^

I can't update the pc at work until I get (hopefully) the promotion in the next week or 2 where I can run any OS i want (Amiga workbench it is then!!!)

I will however test it from home

I always wanted to learn to make a raycaster, never got round to it

Check out my excellent homepage!

I never actually learnt how to build one, I just followed some of the (excellent) tutorials out there. They handle all the maths for you, and you can usually get enough of an impression to be able to tweak/optimize/improve it for your needs.

interesting, do you have a link to a good tutorial or should I just Google it?
Fri, 08 Jul 2011, 14:02
JL235
The first raycasting tutorial (this one) is the one I used to build that.

Egads. I just deleted my post. Not entirely sure how.

@CodersRule: SoCoder was having connection issues for me a minute ago... maybe your post didn't get sent or something?

No, it was sent!

Forum-Post-Delete's a very "click it once, BANG! And the post is GONE!!" button, isn't it.. Perhaps it's time to move it inside the Edit thing, like in Comments..


I love the Raytracer, really well done!
It's a shame it's doing that "little blue line" thing. A 0/1 number issue, perhaps?
*shrugs*
Maybe it'd be easier if you artificially pad out the graphics by a pixel, to hide the line?

I think it's a rounding problem. Currently one of the values is rounded, if I floor it instead then it moves the issue to different walls. Ceiling doesn't help either.

I'll look into it, or feel free to edit the project and debug my code.

There is also a secret fullscreen version available here, but don't expect fullscreen urls to work forever (they might change)!
Fri, 08 Jul 2011, 15:40
Jayenkai
Mmmmm.. fullscreen!!!
Let us know once that's a perma-feature

It needs a bit more polishing, like when it loads the background moves. We also need to come up with a symbol for it on the player.

There is also the issue about someone playing a game, then wanting to go fullscreen. They will lose their progress.

I have also added 'conanical movement', which is essentially 'Shining in the Darkness' style movement.

That's cool! There was no button list. Are there any options other than move forward backward and turn?
Sat, 09 Jul 2011, 17:01
JL235
Nope, no other options. But you could freely copy the code and add your own!
Sun, 10 Jul 2011, 10:24

It also now has two movement systems, free and conanical (you can press space to switch), crouch (left ctrl) and a basic zoom (z to zoom out, c to zoom in and x to reset).

I'm planning to build it into a fully working raycasting engine for others to use. Hopefully there will be a suddenly influx of Shining / Wolfenstein games in a few weeks.

... and I've just added a fog, the walls now get darker as they are further away. It looks a lot prettier; I'd really like to build something proper with this.

the game makes me think of castle wolfenstein.

Was this game made before the first Duke nukem?

You added angular motion, It was kinda annoying the first time having to do left, right, left, right, to move at an angle. It looks realy cool.

Reminds me of a Doom game i played when I was 8. just need a chainsaw and an evil alien and you'll be all set, lol.
