[RELEASED]Untitled Little Racing Game aka B-Rally

Postby Sutchig » Tue Mar 08, 2016 4:26 pm

after waiting some time, i made a little racing game (started around Christmas)...

Status is not nearly alpha... its more like a PoC :), as i have only half a hour per day.
But: its playable, has opponents and has a gameover-screen :P

HEX-File is attached, Screenshot too.

Usage:
A - accelerate
B - brake
Left/right - left/right

ToDo:
-Track is only a MockUp, want to use PetitFatFS to stream the track on-the-fly from SD-Card.
-more Signs
-collision detection
-simple AI for opponents
-tuning of driving parameters (lower the increase of speed at higher speeds for instance)
-....

Idea of Pseudo3D-Road is from http://www.extentofthejam.com/pseudo/
Idea of grey floor is from IsleOfManiax :)

some return :

The game is too fast, I cant anticipate the turn, and I cant see other cars.

In my gamebuino the road and gray floors are not so differente. Maiby the constrast in my gamebuino is not good?

otherwise good work man!

Many thanks for your feedback :)

following things are changed (i edited the first post and uploaded a new zip file):
-game speed is slower (est. 2/3 of original speed)
-opponents are slower, too - but not 2/3 ;)
-decreased acceleration (it takes longer to reach max speed)
-changed track mock-up: curves are not that "curvy" anymore, sign slightly ahead of curves

Hope, this is better :)

I forgot: added cpu usage
And contrast (grey) is fine with my gamebuino

It very good.

I can see opponent, and I finish 6!

The gameover screen is prety good ;) !

I change the contrast on my gamebuino and the grey is Good.

I can t wait to see next step.

You plan to share source-code?

only "little" changes...
Switched the background-routine from drawBitmap() to a selfmade routine, which just copies the sprite in the screenbuffer (basically)
gained 10% CPU usage :)

Now each opponent has its own sprite. I used this for a little number above the car - its like to display the place of the car in front of you.

Background should shake, if you're offroad- in Simbuino it doesnt look nice :( but i have right now not the possibility to test this on real GB.
(My son is sleeping now, and therefore the time is over ;) )

I dont know about the very next steps. Maybe petitfatfs (hard to test) or adding gamestates and maybe an ingame menu (thats why i startet V5)
Ingame-Menu and petitfatfs (with seperate tracks) would give the possibility to use dedicated test tracks - curves, hills, sprites etc...

of course, source will uploaded to github :)

//Edit: Background-shake should work now :)

update:

-petitfatfs (you should extract the .DAT-Files at the root of your SD-Card - be sure, its UPPERCASE, i dont know, how petitfatfs handles lowercase)
-collision detection with opponents
-ingame menu with track-selection ;)

tested with Simbuino (again: great tool :)), and Gamebuino with original SD-Card

Straight and Hills are for testing mostly. Lanes, Curves and Mockup are playable (sort of). "Mockup" (TRACK.DAT) has to be unlocked by getting at least 3rd place at Curves. :)

Data format of the dat-files is:
at least 10070 segments (10000 for travel-distance and 70 for lookahead)
each segment contains of 4 bytes (chars): curvature height lanes signs
where
curvature: something between -8..8 should work
height: -3 .. 3 or so
lanes: 0..2 (will become 1..3 ingame)
signs:
1: sign_right
2: sign_left
3: lane getting smaller

its getting closer to finish, but it still has no name :(
Should i keep "little racer" ?

todo: at least eeprom & some tracks.

//edit: attached a zip of a SD-Card image to test with Simbuino
