GPU Particles

self:set_trail

Client

Draws a ribbon trail behind each particle instead of a quad

local status = self:set_trail(
    state,
    lifetime = 0.3
)

Keep the trail lifetime below the particle lifetime.

Trails reach far from the emitter — raise self:set_visibility_aabb so they are not culled.

Type	Name	Description
`bool`	state	`true` to draw trails, `false` to go back to quads
`float`	lifetime	How long the trail stays behind each particle in seconds, at least `0.01`

Type	Name	Description
`bool`	status	`true` on successful execution, `false` otherwise

Draw glowing sparks with trails

local entity = particle.gpu.create()

entity:set_trail(true, 0.8)
entity:set_blend_mode(particle.gpu.blend_mode.ADD)

Go back to quads

local entity = particle.gpu.create()

entity:set_trail(true)
entity:set_trail(false)

self:set_unshaded

Sets whether particles ignore scene lighting

self:set_material

Sets the material particles are drawn with
