are you saying this tweak is not working? https://feedback.bistudio.com/T151354

@BIS_fnc_KK I think they mean config one doesn't support vector dir/up like scripted ones

I'm very confused. The ontimer and before destroy already have _this with position https://community.bistudio.com/wiki/ParticleArray. Please provide more info and repro example

Leopard is correct. I'm referring to the config one he linked to. It does not have a documented vector dir/up ability like the particle array you are think of.

This is the code im using for the particle generation with an older reference picture of the effect. The large yellow spikes are coming in at random angles:
class CfgCloudlets
{
class Default;
//-------------------------------------------------------------------------------------
class Impactbolt_impact: Default
{

		interval = 100;
		circleRadius = 0;
		circleVelocity[] = {0,0,0};
		particleShape = "tracer\test_bolt_impact";

particleFSNtieth = 16;
particleFSIndex = 13;
particleFSFrameCount = 2;
particleFSLoop = 0;

		angleVar = 0;
		animationName = "";
		particleType = "SpaceObject";
		timerPeriod = .05;
		lifeTime = 0.07;
		moveVelocity[] = {0,0,0};
		rotationVelocity = 0;
		weight = 1.275;
		volume = 1;
		rubbing = 0;
		size[] = {0.01,0.01};
		sizeCoef = 1;
		color[] = {{1,1,1,1}};
		colorCoef[] = {1,1,1,1};
		emissiveColor[] = {{1,1,10,1}};
		animationSpeed[] = {1000};
		animationSpeedCoef = 1;
		randomDirectionPeriod = 0;
		randomDirectionIntensity = 0;
		onTimerScript = "";
		beforeDestroyScript = "";
		blockAIVisibility = 0;
		onSurface = false;
		keepOnSurface = false;
		bounceOnSurface = -1;
		bounceOnSurfaceVar = 1;
		lifeTimeVar = 5;
		position[] = {0,0,0};
		positionVar[] = {0,0,0};
		positionVarConst[] = {0,0,0};
		moveVelocityVar[] = {0,0,0};
		rotationVelocityVar = 0;
		sizeVar = 0;
		colorVar[] = {0.05,0.05,0.05,5};
		randomDirectionPeriodVar = 0;
		randomDirectionIntensityVar = 0;

};
};

class ImpactTest
{
class ImpactDust
{

		simulation="particles";
		type="ImpactSmoke";
		position[]={0,0,0};
		intensity=1;
		interval=1;
		lifeTime=1;

};
class Impactbolt
{

		simulation = "particles";
		type = "Impactbolt_impact";
		position[] = {0,0,0};
		intensity = 1;
		interval = 1;
		lifeTime = 10;

Yes, currently _this will only tell the script the particle position. It does not pass any other variables like the local particle that called it, the particles orientation, etc. I was asking if more info can be passed to the script, beyond what it currently does so the script can control the particle. This will allow for do more than simple operation to control variables.

A brief example would be roughly:
person shoots gun and hits a movable object like a car. This creates large spike in the car. if the car is then moved, I would want to use ontimer script to update the spikes position to move with the car. From my currently little scripting understanding, I can not do that with the ontimer script right now. It only gives me the spikes position.

looks like the parameter exists, it is called

forcedInitialOrientationDir[]

It also looks like it is just vector dir, vector up is just [0,0,1]
