Tutorials:NewDark/Particle effects - Bitmap Disk Fire

This is a very quick and dirty tutorial explaining how to set up a new, particle-only Flame (-208) replacement in Dromed for v1.19. This **will not** work in v1.18 as it relies on the Bitmap Disk particle type added in 1.19

The demo file

An example of the following flame setup is available in this file. It contains the demo.cow file and a bitmap directory containing 'fpuff.tga' - the image used on the bitmap disks. You are free to use the fpuff.tga file in your missions should you want it.

Initial setup

First you need to create a new flame base, an object that will have the various particle components linked to it. Open the Object Hierarchy window and then:

  • Open the SFX -> FireFX tree
  • select FireFX, click Add. In the window enter NewFlame and click OK.
  • select NewFlame and add the following:
AI -> Utility -> Path avoid: Repel

Act/React -> Receptrons
    WaterStim; Min: 0.0; Max: No max; Effect: Slay object; Target: Me; Agent: Me
    KOGas; Min: 0.0; Max: No max; Effect: Slay object; Target: Me; Agent: Me

AmbientHacked
    Radius: 30; Override Volume: 0; Flags: [None]; Schema Name: fire_flame

Game -> Damage Model -> Slay Result: No Effect

Renderer -> Anim Light
    Mode: random but coherent
    millisecs to brighten: 99
    millisecs to dim: 99
    max brightness: 120
    min brightness: 80
    radius: 30
    inner radius: 0
    quad lit: ticked

Renderer -> LightColor
    hue: 0.1; saturation: 0.75

S -> Scripts
    Script 0: AnimLight; Script 1: DoFlameSource; 
  • Click Done.

Where there's smoke there's fire

Now you need to create the smoke and fire particle effects themselves. This is where the new stuff actually kicks in:

  • Open the SFX -> FireFX -> FireParticleFX -> FireplaceFX tree
  • select FireplaceFX, click Add. In the window enter NewFireplaceOrange and click OK.
  • select NewFlame and add the following:
SFX -> Particles

    bm-disk 3rd rgb: (218, 120, 19)
    All other options unticked, except 'particles start launched' which should be ticked.

SFX -> Particle Launch Info
    Launch Type: Bounding Boc
