Drive

Although I obviously can't win this contest, I'm still working on a project for it.

My project is a car driving engine. It's very basic so far - I'm still getting to grips with gosu, having never used it before. So I am starting by editing the star collecting minigame that came with the gosu rubygem.

First steps:

- Get rid of the star class, not needed for now
- Change the acceleration a lot lower, and the handling
- Change handling based on how fast the car is accelerating
- Use the acceleration value to work out a "MPH"
- Draw a working speedometer, with needle, for the MPH value
- Disable turning when the car is not moving
- Brakes, that slow the car down to a stop rather than just stopping
- Handbrake turns - when turning and braking do a little spin

Once I work out how gosu actually works I'll be using this to make my own "engine" (rather than just editing the existing game).

I'll upload a demo or something soon.

Current issues:

- No speed limit, and can't work out a way of setting a speed limit
- Handling is :crazy:
- Handbrake turns: you carry on spinning until you let go of left or right arrow :crazy:

Anyway.

In terms of graphics at the moment I'm using a basic ms paint road, with a GTA2 car sprite.

Major setback: collisions.

Gosu has an object = solid thing, anyone know how to use it? (Or just how to handle collisions in general?)

Ok it didn't go too well.

This is as far as I got: http://bb.xieke.com/files/FailRacer.zip

It's just a hackup of the demo really, I got the speedometer working though.

Hmm, let me have a look through it, and ill see wats there to do :thumb:

nice infinite acceleration xD

the gosu example have limited speed, check the code :3

Edit: forget the input thing, is a different method non valid for that :3

I think chipmunk (sudo gem chipmunk) might help you with collisions and gravity, but if I see any other gem out there, I'll let you know.
