PopcornFX Assets - O3DE Multiplayer Sample

The Multiplayer Sample includes several visual effects (VFX) assets created with PopcornFX. VFX are combinations of particle emitters, textures, materials, and meshes that create all sorts of phenomenae, such as fire, smoke, explosions, electrical arcs, and weather such as rain and snow. This README documents these VFX assets so that you can customize them or deconstruct them to learn how to build PopcornFX assets of your own.

The PopcornFX project containing all the source assets can be found in the following directory: <multiplayer-sample-root>/PopcornFX/PopcornProject.pkproj.

Requirements

The PopcornFX Gem depends on the following additional Gems:

• Atom
• Script Canvas
• EMotionFX
• PhysX
• LyShine
• Starting Point Input

General information

Some of the VFX are split into multiple parts (for example, Blast, Projectile, and Explosion). Splitting the VFX makes it easier to integrate them into varied gameplay scenarios.

Many of the VFX have a Color Intensity property that you can modify to adjust the emissive effect. The emissive effect requires that the PostFX Layer and Bloom components are added to the scene.

Armor Power Up

The Armor Power Up is not a particle system, but rather mesh and shader asset.

The effect is triggered by the Slider property on the ArmorPowerUp.material.

The Script_ArmorPowerUp.scriptcanvas is a test Script Canvas that loops the Armor Power Up VFX.

Bubble Gun

The Bubble Gun VFX is split into the following three parts:

| Blast | Projectile | Explosion | | - | - | - | | | | |

The following properties are available to adjust the look of Bubble Gun VFX:

Property	Description
Global Scale	Scales the size of the VFX.
Distortion Power	Amount of distortion effect.
Trail Lifetime	The lifetime of the smoke. Higher values increase the length of the trail.

Defense Turret

The Defense Turret VFX is split into the following three parts:

| Blast | Projectile | Explosion | | - | - | - | | | | |

The following properties are available to adjust the look of the Defense Turret VFX:

Property	Description
Color 1, Color 2	Sets the color and alpha values for the VFX.
Global Scale	Scales the size of the VFX.
Color Intensity	Sets the intensity of the emissive effect.

The Explosion VFX needs to be oriented with the Impact Normal attribute. You can set this up in Script Canvas.

Energy Ball Trap

The Energy Ball Trap VFX is split into the following three parts:

Build up Projectile Explosion

The following properties are available to adjust the look of the Energy Ball Trap VFX:

Property	Description
Global Scale	Scales the size of the VFX.
Color Intensity	Sets the intensity of the emissive effect.

For a smooth transition between the three parts, each part needs to start at the same frame the previous part ends. You can trigger the VFX in Script Canvas.

Energy Collector

The Energy Collector is a simple single emitter. It just needs to be placed accurately on an entity and triggered by Script Canvas.

The following properties are available to adjust the look of Energy Collector VFX:

Property	Description
Color 1, Color 2	Sets the color and alpha values for the VFX.
Distortion Power	Sets the amount of the distortion effect.
Global Scale	Scales the size of the VFX.

Jump Pad

The Jump Pad is a simple single emitter. It just needs to be placed accurately in a level and triggered by Script Canvas.

The following properties are available to adjust the look of Energy Collector VFX:

Property	Description
Bursts	Sets duration of the launch.
Color	Sets the color and alpha of the VFX.
Brightness	Scales the glow effect of the VFX.
Light Range	Sets the reach of the glow effect of the VFX.
Global Size	Scales the size of the VFX.

To trigger the Jump Pad VFX, the Launch property must be toggled. It doesn't matter if the boolean is true or false. The VFX will trigger if the state of the Launch property changes.

The test Script Canvas script_VFXTestTriggerJumpPad loops the Jump Pad VFX.

Laser Gun

The Laser Gun VFX is split into the following three parts:

| Blast | Ray | Explosion | | - | - | - | | | | |

The following properties are available to adjust the look of Laser Gun VFX:

Property	Description
Color 1, Color 2	Sets the color and alpha values for the VFX.
Global Size	Scales the size of the VFX.
Max Length	Sets the distance at which the explosion occurs if the Hit Position is further away than the Max Length value. This avoids spawning too many particles if the Hit Position is too far away.
Laser Lifetime	Sets the lifespan of the ray.
Hit Position	Sets the world position of the end of the ray.
Hit Normal	The normal of the impact surface that sets the orientation of the explosion.
Distortion Power	Sets the amount of the distortion effect.

Malfunctioning Shield Generator

The Malfunctioning Shield Generator VFX is split into the following three parts:

Idle Build up Explosion

For a smooth transition between the three parts, each part needs to start at the same frame the previous part ends. You can trigger the FX in Script Canvas.

The following properties are available to adjust the look of Malfunctioning Shield Generator VFX:

Property	Description
Distortion Power	Sets the amount of distortion effect on the Explosion emitter.
Frequency	Sets an approximate time (in seconds) between two electric bursts on the Idle emitter.

Speed Power Up

The Speed Power Up VFX is one emitter but three stages that are triggered automatically.

Build Up Idle Fade Out

The following properties are available to adjust the look of Speed Power Up VFX:

Property	Description
Global Scale	Scales the size of the VFX.
Particles Count	Sets the trail particle count. Higher values give the VFX a more opaque look.
Color Wind	Sets the color and alpha of the wind trail.
Duration	Sets an approximate time (in seconds) for the Idle stage of the VFX.
