Legacy:SpriteEmitter
From Unreal Wiki, The Unreal Engine Documentation Site
Used in Emitters to spawn particle sprites. This all-around ParticleEmitter can be used to create smoke, fire, water falls, dust clouds and many other effects.
Some useful combinations of settings can be found in our ParticleEmitter cookbook.
Properties[edit]
The SpriteEmitter class adds only one group to the ParticleEmitter properties.
Sprite Group[edit]
- vector ProjectionNormal
- Normal vector of the projection plane used when UseDirectionAs is set to PTDU_Normal, PTDU_UpAndNormal or PTDU_RightAndNormal.
- EParticleDirectionUsage UseDirectionAs
- Here you can specify how the 2D image should be displayed. See EParticleDirectionUsage enum below for details.
Enums[edit]
EParticleDirectionUsage[edit]
- PTDU_None
- Always rotates the sprite towards the viewer. The sprites will always look the same, no matter what direction they are viewed from. Size -> UniformSize will be forced to True, so only the X component of Size -> SizeScale can be used to scale the sprites.
- PTDU_Up
- Also rotates the projection plane towards the viewer, but in a special way, so the particle's movement direction will always be in the projection plane.
- PTDU_Right
- Like PTDU_Up, but the particle texture is rotated 90°.
- PTDU_Forward
- The particle's particle's movement direction is used as the projection plane's normal vector.
- PTDU_Normal
- The ProjectionNormal is used as the projection plane's normal.
- PTDU_UpAndNormal
- This is similar to PTDU_Normal, but the particles can only be rotated around the axis given by the particles' movement direction.
- PTDU_RightAndNormal
- Same as PTDU_UpAndNormal, but the texture is rotated 90°.
- PTDU_Scale
- Like PTDU_None, but allowes you to turn off Size -> UniformSize so the sprites can have different scaling values for X and Y.
