Yeah true, it's incredible how easy GS is to achieve in Axe compared to ASM and xLIB/DCS

This is looking awesome! Possibly to gain some speed, you could try 2x2 pixels instead of 1x1 and it would get 4 times faster maybe?  You wouldn't be able to use the Axe line function but it sounds like you already have your own :D Me and Eeems were working on a similar game concept earlier but it didn't go anywhere.  I looked into blinded by the dark code but i couldn't make any sense of it :( and they use some sort of tricky algorithm since it can have multiple light sources.

Overall i think this is looking awesome! :D

* DJ Omnimaga wonders if that is related to their secret project or something :P

The problem with grayscale shadows is then you can see the whole map, regardless of where you are standing.  Then the shadows become more of an effect that a gameplay mechanic. 

(Is gameplay mechanic the right term here?  I'm not really sure...)

I thought the entire idea of games like these is for you not to know what is around you without actually physically going there.

Yeah true, although maybe he plans to use the shadows to hide enemies and stuff, idk (Like Starcraft 2).

Btw nice to see you around again on the forums Michael :D

Well, he could make it so anything in the shadows is grey, and the walls that you can see are black.

Any optimization suggestions, please?
(I'm using a variant of Bresenham's line algorithm, for those interested)

It looks awesome, but why are you using that algorithm? It could very well be faster to set the initial screen and adjust the start/end points of the Line( function (which already uses Bresenham's algorithm).

I'm using the algorithm to test when the shadows should start.  The algorithm tests all the points in the line, and when it encounters a black pixel, it switches over to the built in line( function to draw it.

Okay, grayscale it is!

Anybody know where I can find a TI-86 emulator?  I wanna try Blinded by the Dark.

Wabbit supports 86s, I think.

And btw, that looks awesome :D

EDIT: Yep, just tested. 86 works perfectly on Wabbit. Even 85s, even though they use the 86 skin.

I thought 86 support was limited and 85 absent?

After procrastinating for days (curse you, cuberunner!), I finally managed to implement a variant on Builderboy's suggestion and made the game check every two pixels for collisions.
Which means that now, instead of being excruciating, it's just a little slow!  (Yay!)

Because I couldn't decide between black or grayscale shadows, I added both.  You press alpha to alternate between the two.  (I got a little lazy implementing it, so you have to come to a complete stop, press alpha really quickly if your emulator is fast, then start moving for it to switch).

Next:  Collision detection.  And plot.  And more optimizing, if possible.

Looks good.  Like I said earlier, if you're going to do greyscale shadows, I would make anything in shadows grey, otherwise there is no point.
