Can someone tell me why this particle system call doesn't work? llParticleSystem([ PSYS_PART_FLAGS, 0 |PSYS_PART_EMISSIVE_MASK |PSYS_PART_INTERP_COLOR_MASK |PSYS_PART_INTERP_SCALE_MASK |PSYS_PART_TARGET_LINEAR_MASK , PSYS_PART_START_COLOR, <1,1,1>, PSYS_PART_END_COLOR, <0,1,0>, PSYS_PART_START_ALPHA, 0,8, PSYS_PART_END_ALPHA, 0,5, PSYS_SRC_BURST_RATE , 0.0, PSYS_PART_START_SCALE,<.2,.2,.2>, PSYS_PART_END_SCALE,<1.5,1.5,1.5>, PSYS_SRC_BURST_PART_COUNT, 10, PSYS_SRC_TARGET_KEY, vehicle, PSYS_SRC_ACCEL,<0,0,0> ]); It compiles OK, but then fails with runtime error: PSYS error: Rule 5 error, PSYS_SRC_ACCEL needs vector data. As I understand it, PSYS_SRC_ACCEL is ignored when a target is used. I have it there with vector data. Removing it does not change the error. I'm sure I'm just not seeing something.... but, yeah, I'm not seeing it. Also, what should the particle system call to turn off the particles look like?
