Top-down surface friction demo

Post by Azhukar »

Box2d friction joints used to emulate top-down friction. Works even with mobile surface bodies.

This is very awesome.

I am wondering if there is a way to look at the source from a .love file. I am new to this, but would like to learn as much as I can. This would be great for a top-down racing/driving game.

Change the extension from a .love to a .zip, then you can view it as a normal .zip file.

Hope you see this!

I was wondering if I could use your code for turning like how you rotated then went forward. I wanted to use that code for something I'm making. I'm not sure if I'll share it on here but if I do I'll give you credit in code and in the game :) Great idea too!

Code: Select all

if signature = true then
    print(signaturetext)
else
    print("Error: Signature Not Found")
end

On second thought, Took a look through your code and I've realized it much harder the way you set it up because you wanted to make that section orientated to your "game" thing so is there a chance you can message me or give me a bit of help on how to do that? If so that would be great thanks :)

Sure! You can use it! I'll show you the important parts:

Code: Select all

Direction = math.atan2( ( ObjectY - TargetY ), ( ObjectX - TargetX ) )
Then you set that as the direction. Good luck!

I'm very confused is it alright if I put this up on media fire and you can download it and give me some help?

I tried to make a box2d car game once, but yours is way better.
