Float |
Variation of the position in Yof the particles emitted by this
emitter |
| angle |
Float |
|
| nbPartFrame |
Int |
Number of particles created by frame |
| typeEmt |
String |
Blend applied to the particles ("alpha"
for ALPHABLEND, "light"
for LIGHTBLEND) |
P2D_ReglerEchelle(e,
echelleXIni, echelleYIni, ecartEchelleXIni, ecartEchelleYIni, dEchelleX,
dEchelleY)
Parameters size of the particles emitted by the emitter e.
| e |
TEmetteur |
Emitter to which we want to apply the parameters |
| echelleXIni |
Float |
Coefficient by which we want to multiply the width of the basic
image |
| echelleYIni |
Float |
Coefficient by which we want to multiply the height of the basic
image |
| ecartEchelleXIni |
Float |
Variation tolerated in the width of the particles during creation |
| ecartEchelleYIni |
Float |
Variation tolerated in the height of the particles during creation |
| dEchelleX |
Float |
Evolution of the width of the particle (0: remain stable, <0:
narrows, >0: grows) |
| dEchelleY |
Float |
Evolution of the height of the particle (0: remain stable, <0:
narrows, >0: grows) |
P2D_ReglerAlpha(e,
alphaIni, ecartAlpha, dAlpha, ecartDAlpha)
Parameters alpha of the particles emitted by the emitter e.

Alpha allotted to the creation of the particles |
| ecartAlpha |
Float |
Variation tolerated in alpha allotted to the creation of the
particles |
