floaty drift vehicle physics

[CR4SH3D]

hey guys

im working on a new demo at the moment but im stuck on how to use the physics to allow a vehicle to drive properly as well as drift around turns, think of something like wipeout for an idea of what i mean

are there any really useful links, tutorials or librariess to achieve this? ive had a look for hours and havent turned up anything i can follow yet

a basic .love would be awesome

take it easy

I would imagine you just turn down the friction and keep gravity at (0,0)

but working out angles and the heading using sin etc? i dont know how that works, any ideas?

this is writen for a game in java but the math's is just the same i guess.

it explains it well

ive had a go and think it should work but the values arnt numbers :S does anyone have any ideas?

[TechnoCat]

Code: Select all

craft:setX((craft:getX()) + (xvelocity))

velocity~=position

[CR4SH3D]

so how do you go about using it then? the angles are messed up

[TechnoCat]

I pretty much completely rewrote it, but have a look at what I did here.

thanks, it seems to have lost the drifting using the friction value though, how do you implement that?

[TechnoCat]

Instead of using setVelocity, might try using applyImpulse or something similar. Or a hybrid of the two.
