Is there a RayCast like node for a projectile motion?

Before I try to implement a “ThrowCast” Node myself, is there something like this already inside of Godot?

I want to calculate the collision of a “stone throw” similar to the calculation of the collision by a ray cast. The math of such a collision calculation isn’t to complicated but I want to avoid implement something if it already exists.


Nope, it will be a great idea!

There is the test_move function of KinematicBody, but I’m not sure if that’s what you’re looking for.

I’ve coded a 2d Version of the “ThrowCast2D” Node already and am currently porting the Logic to 3D as well. I think I could make a Simple Addon which provides these Nodes including a SampleScene to show how to use them.
But at least I have to learn, how to create a Addon and add it to the asset store…

I created the Addon (a C# Version and a GD Version)

  • the C# Version is well tested
  • the GD Version is backported from the C# Version. Since I’m working most of the time with C# the GD Version may not as good as the C# Version - but at least the DemoScene works. The C# Version may be slightly faster, it uses a optimized way to update the mesh which I can’t achieve in GD

Both Addons are send to the AssetStore but are currently in the approving process.
You could get them at my github pages:
