A spheroid-shaped attractor that influences particles from GPUParticles3D nodes. Can be used to attract particles towards its origin, or to push them away from its origin.
Particle attractors work in real-time and can be moved, rotated and scaled during gameplay. Unlike collision shapes, non-uniform scaling of attractors is also supported.
The attractor sphere's radius in 3D units.
Note: Stretched ellipses can be obtained by using non-uniform scaling on the GPUParticlesAttractorSphere3D node.
