Is there a way to change the extents of a Particles2D node's emission shape from script?

I’d like to set the size of the particle effects based on the collision shape of the body that they surround at the time of instantiation.
I can’t seem to access anything about the node’s emission shape from script.

For example (albeit a crude one):

var p = particles.instance()
var size = entity.get_shape().extents
p.extents = size

The emission shape is a property of the ParticlesMaterial. If you hover your mouse on the material, you’ll see the property name is process_material. Hovering on the emission shape shows emission_shape. Since you said “extents”, I assume you’re using a “Box” shape, in which case the extents property is emission_box_extents.

So, to set it:

$Particles2D.process_material.emission_box_extents = Vector3(2, 2, 2)

All this and more in the ParticlesMaterial reference.

Works great thanks :stuck_out_tongue:
