3D particle emitter

Display a large number of particles in 3D to create visual effects in a 3D game.

Authors and contributors to this extension: D8H.

3D particle emitters let you create and display many small particles to simulate visual effects in your game — like fire, explosions, smoke, dust, magic, rain or snow.

The parameters of the object can be configured in multiple different ways to create a specific desired effect. GDevelop will give a set of a pre-configured 3D particle emitters that you should try first.

Particles are emitted along the local Z axis of the emitter: upward by default. Rotate the instance to aim the emission (for instance a rotation of 180° on the X axis emits downward, 90° on the Y axis emits toward X). The size of the instance has no effect: particles are emitted from a single point, or from a disc when the "Emission zone radius" property is set (useful for rain or snow falling over a whole area).

Use these 3D particle emitters in 3D games. For 2D games or particles that appear on a game's 2D user interface, use the 2D particle emitter object instead.

3D particle emitter

Display a large number of particles to create visual effects (fire, explosions, smoke, magic, rain, snow...). Particles are emitted along the emitter's local Z axis (upward by default): rotate the instance to aim them (180° on the X axis emits downward). The instance size has no effect: use the "Emission zone radius" property to emit from a whole area.

Object properties

  • Start color (🎨 Color). Default value is 255;0;0.
  • End color (🎨 Color). Default value is 255;255;0.
  • Start opacity (🔢 Number, Dimensionless). Default value is 255.
  • End opacity (🔢 Number, Dimensionless). Default value is 0.
  • Flow of particles (particles per second) (🔢 Number). Default value is 50.
  • Start min size (🔢 Number, Distance). Default value is 10.
  • Start max size (🔢 Number, Distance). Default value is 20.
  • End scale (🔢 Number, Dimensionless). Default value is 0.
  • Start min speed (🔢 Number, Speed). Initial speed of the particles, in the emission direction (the local Z axis of the emitter). Default value is 100.
  • Start max speed (🔢 Number, Speed). Default value is 100.
  • Min lifespan (🔢 Number, Duration). Default value is 1.
  • Max lifespan (🔢 Number, Duration). Default value is 2.
  • Emission duration (🔢 Number, Duration). 0 emits forever. Default value is 5.
  • Particles move with the emitter (🔘 Boolean). When checked, the particles already emitted follow the emitter when it moves or rotates. Leave it unchecked for rain, snow or smoke that must stay where it was emitted while the emitter follows the camera or a character.
  • Spray cone angle (🔢 Number, Angle). Spread of the particles around the emission direction, which is the local Z axis of the emitter (upward by default, rotate the instance to aim it). 0 or more than 180 emits in every direction, unless an emission zone radius is set: then 0 emits straight. Default value is 30.
  • Emission zone radius (🔢 Number, Distance). Particles are emitted from a disc of this radius, perpendicular to the emission direction. 0 emits from a single point. Use a large radius (like 1000) for rain or snow falling over a whole area. Default value is 0.
  • Blending (Choice, one of: "Normal", "Additive", "Subtractive", "Multiply", "None"). Additive makes particles glow (fire, magic, energy). Use Normal for rain, snow, smoke or dust. Only applied when the object is created. Default value is Additive.
  • Gravity top (Choice, one of: "Y-", "Z+"). Z+: gravity pulls particles down along the Z axis (the usual choice in 3D games). Y-: gravity pulls particles toward Y+. Default value is Y-.
  • Gravity (🔢 Number, Acceleration). Acceleration pulling the particles in the direction given by the gravity top. 0 disables gravity. Default value is 0.
  • Delete when emission ends (🔘 Boolean). Delete the object once the emission duration is over and every particle disappeared. Uncheck it and set the emission duration to 0 for a continuous effect like fire, rain or snow. Default value is true.
  • Start min length (🔢 Number, Dimensionless). Number of past positions kept to draw the trail, one per frame: the visible length is this number multiplied by the distance traveled by the particle each frame. Default value is 120.
  • Start max length (🔢 Number, Dimensionless). Number of past positions kept to draw the trail, one per frame: the visible length is this number multiplied by the distance traveled by the particle each frame. Default value is 120.
  • Render mode (Choice, one of: "Billboard", "Trail"). "Image facing the camera" draws each particle as an image. "Image following a trail" stretches the image along the path of each particle (sparks, rain streaks). Default value is Billboard.
  • Follow the object (🔘 Boolean).
  • Tail end width ratio (🔢 Number, Dimensionless). Default value is 0.
