Line of Sight Mod!

[Kegluneq]

What's this? A new mod? That's craaaazy!

Anyway, I've wanted to make this for quite some time, only I didn't actually start trying for real until yesterday.

Here's a few screenshots so you know what to expect:





Get it here! Or get it ghostless!

Changelog:
v1.2: Fixed the bugs introduced in v1.1 and fixed the boss room.
v1.1: Changed ice blocks to not block line of sight. As a result, ice levels are now easier, and you can see what the prize at the craps house is.
v1.0: Game over fixed, pause screen fixed, item get effects fixed, dark levels fixed.
v0.3: Line of sight algorithm improved, shadows look much cleaner now.
v0.2: First release.

This is like a mod I wanted to make, only you can still see behind you.

you should make a verson where you can't

[Sparkle]

Agreed with Mars, and yay! this looks like it will be lots of fun, given my playing style. c:

So Spelunker has eyes in the back of his head I see

also you should try to make it less ugly, I mean all that sudden black everywhere is really.... eh

its probably a bit complicated to program, but maybe you could try adding a dithery fade to the shadows, like the ice levels have (see attachment) and shading the far sides of the blocks or something

pickiness aside this looks pretty cool, i swear someone else has made something similar though

yeah I can help with that if you want

[Kegluneq]

I thought about doing something like that, but didn't figure out exactly how, at least not with the method I used to implement the LoS. EDIT: Check that, I think I figured something out.

I thought about making it so that you could only see in front too, but I realized that I would just keep hitting left and right and it just seemed kinda unnecessary.

[Bae]

you know what the best approach would be for this LoS thing?

make spelunky into a first person adventure game yep simple

[Wonkyth]

Dude, this is awesome!
Damn, I wish I had time to play it! 

[halibabica]

Haha, very clever!  I hope you can work out all those bugs.

[Wonkyth]

Also, what method are you using?
Triangle fans?

[Kegluneq]

Triangle fans yes, drawn with primitives. There are method for using textures to draw the primitives, I'm trying to figure out how they work right now.

EDIT: Oh so that's how it works. Then I have no idea how to get a fade effect.
Specifically, the method I'm using is draw_primitive

EDIT 2: Version 1.0 is out! Game over fixed, pause screen fixed, line of sight improved, misc. item get effects fixed, dark levels should be fixed. Awaiting testing results.

[Moloch]

Cool stuff! I just played a couple levels so far.

[Kegluneq]

Updated to v1.1!
Changed ice blocks to not block line of sight. As a result, ice levels are now easier, and you can see what the prize at the craps house is.

Bug: Thanks to my ice block change, UFO lasers will pass right through them. I kinda like it though, so I probably won't change it unless you all think it really needs to be done. It adds back a liiiiitle more of the difficulty I took away by making ice see through to begin with.

Got this entering the final boss room.  Also, ice can no longer be blown up with bombs, and you can see the trap doors of the spike ceiling trap in the temple.  Cool mod, though!

[Kegluneq]

I'm aware of the boss room bug, it's really confusing me. Those other ones should be easily fixable though, I'll get on it tonight!

EDIT: Fixed! The boss room too!
