Wow that was easier then I thought it would be, I don't fully understand the ins and outs, but I got it working. For those interested what I did to fix was as iForce said, use the the normal from the raycast, I then created a method based on http://www.iforce2d.net/b2dtut/top-down-car b2Vec2 getLate...

ah, I see. That only works in the example because the ground is always assumed to be straight downwards. I guess you would have to use the velocity relative to the current ground normal. Any tips on doing that, I have some brute force ideas, but a nice elegant solution would be nice, to keeps thing...

Further investigation shows the linear velocity y actually increases as it goes up the slope which makes complete sense, which it turn is throwing of the distance calculated via this line off. distanceAboveGround += 0.25f * m_hovercarBody->GetLinearVelocity().y; So I'm guessing I need some sort of w...

Ah, that's a good point, the output is the same, I never noticed the issue with the distance when its on a slope, its weird as when I drag it along the ground with the mouse, the distance goes into the minuses even though its not changing. A good starting point would be making sure the distance is m...

Hi iForce, thanks for helping me out over at the hovercraft tutorial, I feel I might be able to make a cool anti gravity game out of it which would be sweet. I just got a couple of hurdles I'm struggling with, I have the ship rotating based on the angle of the body below it,I am using AngularImpulse...

Hi iForce,

Do you have any advice on how I could create a destructible building in R.U.B.E, Im hoping to make this building tall too

Yeah related by joints

I am trying the function but the translate function is throwing an error

Line 36, col 25: No matching signatures to 'mv(const uint, const uint)'
Line 36, col 2: No matching signatures to 'translate(body[]&, int)'

Thanks!

Hi IForce

I need help moving related bodies, as I have copy and pasted model on top of model, but now need to move each model independently, is there any script which could achieve this?
See attachment for further clarity

Try setting the fixtures filter group index to -1

Yeah I'll see if I can get any info on improving it through ai, I'd like tosee the boxing game complete too, look pretty fun.

intrusion 2 is a great example of what I'd love to achieve, but its way beyond my current knowledge, I'll keep trying though!
