Vehicle Builder

SP4CEBAR 2022-09-13 08:05 (Edited)

Drag some parts together, build a vehicle, drive away!

click here to read what's new

you can mod it entirely using GFX designer, click here to learn more

In a future version, it could calculate the center of mass, and the center of lift, and I could save some coordinates so that I can attach some forces to it, or my gun system

Now I really want to merge this program with my game engine, but 8000 tokens + 15000 tokens... something tells me it's not gonna fit

Notes:
- If you use more than 64 sprites, it's going to start at zero
- wheels are already round, why rotate them, they will be separate sprites in a future version
Known bugs:
- If your image doesn't fit in memory, it's going to throw an error,
- Some sprites seem to overwrite others, that can't be good
- Some parts have a wrong sprite size

Very cool!

so cool, would be even cooler if there were more rotation

SP4CEBAR 2022-09-14 09:58

@G9, You mean more rotation frames in between?

SP4CEBAR 2022-09-14 10:07 (Edited)

@gamelegend, I know about that one, it ran out of memory because it detected a large "sprite" size, I could add a calculation before the process to figure out how many rotation frames can be drawn for any given size before it would run out of memory
this process just takes a lot of memory

Your vehicle has quite a lot of empty space in it, so that will result in an inefficient memory usage, i'm not going to change that that because I hate working with dynamic files, they make everything 10x more complicated

What I am going to do however, is exclude wheels from the process, your sprite is in luck, because it would get a lot smaller, wheels are already round, so why rotate them, they will be added back as separate sprites that can be animated and move separately with suspension

I've got a concept for a new collision system (I just remember that I've already used "NewColl" as a subprogram name)

Take the coordinates and the size of a sprite, loop through each of the cells it collides with, and search if cell.c(x,y) is collidable then turn it into a sprite, when all of these are sprites you could use sprite hit a to b, I think this way could be quite efficient, but if a vehicle fits in one sprite, then it gets pretty hard to rotate it according to the terrain

Update:

• rotation frames scale with size:
  • for big sprites only a few frames fit on memory
  • for small sprites you could have quite a lot of frames (1200 if it's just one character)

Update:

• trashcan for the editor to which items can be dragged to delete them, and it can be tapped to clear all
• wheels are now separate sprites! So animated wheels and suspension are now possible
• "wrong sprite size of an item" bug fixed

Known bugs (remaining):
- Some sprites seem to overwrite others

Feel free to modify this program.

You can and add your own vehicle parts entirely from GFX designer, you don't have to modify any code.

Here are a few notes:

• make sure to leave in both grass characters and their palette, so that the game has terrain and a background
• also leave in the button slices and trashcan from the vehicle assembly menu,
• make sure to leave in some whitespace in between the items in the item selection bg image, this is needed for it to detect the size, it currently only supports a size of 8x8 and 16x16, but that could be changed in code
• the whole rotated character always uses palette 1
• the wheels are separate sprites, so they could have a separate palette, to add it add this code before the third main loop, after where the variable "WHEELS" was declared:

  FOR I=SPRITE0+2 TO SPRITE0+2+WHEELS
  SPRITE I PAL [insert palette number here]
  NEXT I

if you want to modify the code here is a short explanation:

The program has three main loops:

1. for the vehicle building,
2. for the conversion process
3. for the gameplay

All you need is the third loop, probably
I should make an array to which I can write all the sprites from the vehicle building so that they can be given an in-game purpose (sprites are overwritten and RAM is full)

The code is a bit of a mess (I didn't clean up) (and it's based on my first character rotating program, that I wrote in original Lowres Coder last month

So is the empty space between the actual vehicle and the wheel that I accidentally added counted as part of the vehicle?

SP4CEBAR 2022-09-16 08:36

No, that's already been fixed, I was talking about the item selection page (which you can edit in GFX designer! to add your own components)

i really did not know what i was doing when making a car. but it felt good making something orignal. this is truly a masterpiece of a game

Thank you!
