Ask help to fix errors (game with wolf3d) - 1micha.elok - 02-05-2025
Hi, Marcus
You may reply me on weekend when you are not at work. It's not urgent
I am making an animation of a night driving with the wolf3d library.
click the images to zoom in
Could you please help me :
- I don't know how to fixed some bugs
1. the car is not turned smoothly on turn#4 and turn#3
2. the zombie animation is overlapped
- I don't know how to put the sky image as a background ( not as a tileset)

I'll have a closer look at the problems this weekend, but I'll comment on one of them now.
It's not possible to draw a background image, because the library (the part written in C) clears the screen when it renders its stuff. I can release a fix that doesn't clear the screen, or I can add a function to set a background image? I can render the image on the "inside of a cylinder" to make it look a bit more 3d (the n6 gloom library did this).
RE: Ask help to fix errors (game with wolf3d) - Marcus - 02-05-2025
One way to fix the sprite animation is to apply these changes. After loading the map:
Code:
' Load map.
flags = w3d.LoadN6Map("assets/map.txt")
' marcus: set colorkey of image used for sprites to black
set image colorkey w3d.n6.imgDefs[7].img, 0, 0, 0In the game loop when updating the frame:
Code:
' zombie, it'a bug, the zombie animation was overlapped
if vCrossFrameCounter = 0
vCrossFrame = (vCrossFrame + 1)%12
dst = w3d.n6.imgDefs[7].img
set image dst
' marcus: clear with colorkey color
set color 0, 0, 0
cls
set color 255, 255, 255
draw image zombie, 0, 0, vCrossFrame
set image primary
endif
vCrossFrameCounter = (vCrossFrameCounter + 1)%5RE: Ask help to fix errors (game with wolf3d) - 1micha.elok - 02-06-2025
Thank you for your time, my friend,
The zombie attack is just pretend
A lonely night driver speeds ahead,
While undead hands reach for his head
But don’t you worry, it’s just a game,
No rush at all, there's no real pain
Take your time, no need to race,
The zombies brought snacks—they'll save you a place

While adding a "sky" feature to the wolf3d library I discovered a bug that causes a really bad crash (no error message)
I'll return with a new version of the library and n7 when I've located and fixed the problem. I also want to add some new commands for transformations when drawing polygons and ... maybe add support for loading mp3 files.
RE: Ask help to fix errors (game with wolf3d) - 1micha.elok - 02-08-2025
I'm sorry, the new request made the program fall,
A sky for Wolf3D—it crashed it all
But hearing your plans, I’m truly impressed,
An enhanced new version? That sounds the best
MP3 support? Oh, what a delight,
Bringing new sounds to the game feels right.
When release day comes, I’ll give it a spin,
Excited to see the great work within

Need to say that I haven't forgotten about this
The bug I discovered is quite nasty and I'm still working on it.
