2D car physics engine feedback wanted

[pixeldriver]

Our lass was away last night and daughter in bed so thought id have a bash at making the handling engine i used for zombies brains automobiles abit more stable. Managed to nearly eradicate the snapping back to the correct angle issue, it now usually slides back smoothly for most of it. Added instability when braking so you can brake and to make the car slidey. Mostly stopped the issue were if you drive in a straight line the tap an arrow key it would slide right to one side which looked really lame.

If you touch the kerbs it makes your car loose grip and the car back fires depending how your driving it

See what you think.

Did you develop this yourself?

[pixeldriver]

Yup all my own doing although took ages for it to click in my head how to do the sliding part. I remember when me and louie was doing that micro machines game and he told me the theory of how to make a car skid but i cudnt work it out myself and i dont like to just paste other peoples code ya know.

Its using the original race car movement, but lots of events and also a fake and real car object for the sliding. Like i said its a more polish version of the one i made for Zombies, Brains and Automobiles.

Update

Did some work tonight, made it really hard to steer while on the brakes, also if you go onto a track kerb it also makes it harder to steer now.

Do you like it?

another update

did abit more research into car physics to see what else i can achieve. Once it's all done I will post it for anyone to use in there games if they fancy making something from it or maybe a collaberation with someone. Ok so changed the speed in the latest build so it works alot better. Another thing to make it abit more realistic is that if your accelerating then left off the accelerater the weight shifts making it more likely to slide aswell.

I'm going to keep researching into this stuff to keep adding bits till it's as realistic as you can get in a 2D game

Nice! Are you using another object for the skids like most people do?

[Hoj]

It's a pretty nice edit of the race car movement engine. Why don't you try to create on from scratch using a static object? I'm not sure how difficult that would be, with the directions etc? It can't be easy having to hack the race car movement either

[pixeldriver]

Oh no i couldnt handle doing a static engine as wouldnt even know were to start. It is abit complicated messing with the car movement but at least it gives me a base to work from. Ive added some meters now aswell so you can see whats going on as your driving.

I think what i like about this is its like an inbetween version of albins crazy complex 360 car movement which i couldnt understand any of. I wish i could be bothered to work on doing gt challenge again as loved that. I need someone who enjoys track design and stuff like INI and all that.

Any ideas on how to make this better?

Update

Added instability at high speeds, so if you come to turn at high speed you will slide alot more.

[pixeldriver]

update

added understeer, if your accelerating and come to turn if your going to fast your car will run wide as in real life. The parameters might need altering as its abit hard to go around the course without either understeer or oversteer.

I've also changed the turning point so its abit closer to were the front axel would be instead of in the center as before.

Let me know your thoughts

Uploaded a video to youtube last night to show some of the physics and how to do them.

[Hoj]

I am playing this btw

I think you should make GTM3.

[pixeldriver]

Haha Ah great stuff! What do you think to the latest version?
Also whats GTM3?

[pixeldriver]

Nice! Are you using another object for the skids like most people do?

Yeah im using a fake car which follows the real one which has race car movement. I alter the angle of the fake car for the skidding part. Is that what you meant albin?

Btw thanks for the great response, anything you can see to improve on it?

[pixeldriver]

Come on guys give it a bash please

[Hoj]

I have. I'm waiting for it to all be static O_O

[pixeldriver]

What difference is it been static going to do? Surely im still gonna have to rotate the object to turn into a corner aint i? I dont get how it would be different. Confused.
