Q3D V-2.4 [3D Physics + Skeletal Animation UPDATE]

From what I've played around with, you can use the physics with Q3D and have cylinders, cubes and spheres.

What you can't do is load in a 3D model and use the shape of the model for collisions.

I can import my 3D track but it only lets me set the shape as a cube (flat)

In order to get a track working you would pretty much have to build an in-game track editor. Either that or create a script that can transform a track mesh into a bunch of box primitives. It isn’t impossible, but you might have to get a little creative with simplifications.

wow your right. that's kinda disappointing.

A script to add shapes would be out of my skillset I think :( Especially as it seems tricky to line things up in Q3D

how complex do you need the physics to be?

I know you can use the raycast object to get the angle of a face and it's height. provided you don't need super realistic physics you could make a raycast above the car down to the ground. you could then compare the change of height and add to an upward momentum. and then if it lowers apply a gravity to this same value. and if the car falls below the raycast (below the level)then set the cars height to the level. (this is just the idea of course) It's not the ideal solution. but it's better than nothing.

This is a great point! There are a ton of good Unity hovercraft tutorials. Here's one that seems to have all of the key bits in one page:

Your track would be a perfect fit for this kind of driving mechanic. It would be great to have a Construct-based 3D racing game with nice smooth tracks.

is it possible to repeat a texture over an object? I have a cube that I want to turn into ground. because the texture repeats I should not have to make the texture the size of the ground. i looked at the UV repeat function but it does not seem to cause the texture to repeat. just shrink

Thanks for the tip! it repeats perfectly!

I am going to copy your sample code there as well. I've struggled to get the camera working in my project too.

wow I owe you cjbruce for telling me about Dot Products. now that I know how to do basic computation of them I have found more uses for it.

My project is a competitive shooter in the style of Midi Maze from way back in the DOS days. I realized though I would need some modern Quality of life things from modern games. such as knowing what direction you are getting shot at.

I use a Dot Product the same way I do to know what direction a sprite should face. but using the bullets position instead of another player. I then turn that into an angle and use that to position a hurt effect on the players screen.

You are very welcome! Dot Product is super useful in both 2D and 3D games. The Cross Product is also useful if you ever want to incorporate spinning things.

Looking great! I feel like it could use a little more silhouette contrast against the dark background.
