To get the vertical line, just rotate the sprite 90 degrees right and then you add the line you want. The result is the vertical line from bottom to top.

Code: [Select]
[whatever your sprite is]->Pic0
.L is the line number (0=leftmost, 7=rightmost)
{RotC(Pic0)+L}->V
.V is the bit mask of the vertical line. MSB = bottom pixel, LSB = top pixel
EDIT: When you only use that sprite you said it doesn't need to be turned because it is the same then.

And L (without *8 ) should be correct.

On an off-topic note, I like how the texture has no outline in the screenshot above. I wish more raycasters used such textures so games won't always look like you are in a tunnel.

Yeah, it is probably the fastest way to do it. If you don't need the sprites anywhere else, just store them rotated. That is faster and takes less memory. ;)

Btw, your raycaster looks awesome so far. I built one myself last week. Does yours run at 6 mHz or at 15 mHz?

Yeah I know. I just thought the lack of an outline made it unique lol. And sadly I can't help since I never used raycasting before.

What do you mean with a "a line with a different size"? One that is wider than one pixel?
When you only need vertical or horizontal lines, you should use the Rect( command. It is a lot faster than Line( and you can adjust the width.

I don't know, can you post the solution you came up with so maybe we can optimize that.

I extract the number (1 or 0) and i divise the size of line by 8 enregistred in W and I drawn the pixels multiplicated by the number W ...it's very long...

:for(8 )
:Size/8->W
:extract the number (with routine unoptimisable) 0 or 1
:for((0 or 1)+W)
:pxl-on(X,Y) or pxl-off(X,Y)
:Y++
:End
:End

i make this, I don't post the code in the totality because my 84+ is not accessible.

Why do you have to multiply with W at the end? I don't get the point of that. Can you post that part of your code?

Are you doing clrdraw every frame? That would make the pxl-Off redundant.
