Alright so I've been stumped on this one for awhile, perhaps its because I don't understand geometry very well but I simply want these entities to spawn in random around where the client is looking at. But no matter how much I try they always spawn randomly but also clearly in line with one another at an angle. Any idea what I'm doing wrong here? Or any pointers?

Spoiler

 	

	ArtillarySmokePos2[0] += GetRandomFloat(125.0, 250.0); //Done
	ArtillarySmokePos2[1] -= GetRandomFloat(125.0, 250.0); //Done
	TeleportEntity(ArtillarySmoke2, ArtillarySmokePos2, NULL_VECTOR, NULL_VECTOR);

        ArtillarySmokePos2[0] -= GetRandomFloat(250.0, 500.0); //Done
	ArtillarySmokePos3[1] += GetRandomFloat(250.0, 500.0); //Done
	TeleportEntity(ArtillarySmoke3, ArtillarySmokePos2, NULL_VECTOR, NULL_VECTOR);

	ArtillarySmokePos3[0] += GetRandomFloat(125.0, 250.0);
	ArtillarySmokePos3[1] -= GetRandomFloat(125.0, 250.0); //Done
	TeleportEntity(ArtillarySmoke4, ArtillarySmokePos3, NULL_VECTOR, NULL_VECTOR);

	ArtillarySmokePos3[0] -= GetRandomFloat(250.0, 500.0); 
	ArtillarySmokePos3[1] += GetRandomFloat(250.0, 500.0); //Done

Note: My first issue was all the random points drifting up and to the right of the clients aim and I realized that was because I was just adding to the same vector. So I made 3 of them hense the ArtillarySmoke 1 - 3.

[hmmmmm]

Bit confused what you're doing with your code. You teleport ArtillarySmoke2 to the position ArtillarySmokePos2 but then also teleport ArtillarySmoke3 to ArtillarySmokePos2. Same with ArtillarySmoke4 and ArtillarySmokePos3. Then you add to ArtillarySmokePos3 even though you're not using it (unless there was some code cut off).

You could try doing something like this:

PHP Code:

for (int i = 0; i < 2; i++) {

    ArtillarySmokePos2[i] += GetRandomFloat(-250.0, 250.0);
    ArtillarySmokePos3[i] += GetRandomFloat(-250.0, 250.0);
    ArtillarySmokePos4[i] += GetRandomFloat(-250.0, 250.0);

}

TeleportEntity(ArtillarySmoke2, ArtillarySmokePos2, NULL_VECTOR, NULL_VECTOR);
TeleportEntity(ArtillarySmoke3, ArtillarySmokePos3, NULL_VECTOR, NULL_VECTOR);
TeleportEntity(ArtillarySmoke4, ArtillarySmokePos4, NULL_VECTOR, NULL_VECTOR); 


I'd also recommend doing some debug prints to see what positions they all end up at and whats happening at every stage of the code.

As hmmmmm mentioned, you're never changing the 2nd (or third, w/e) index of ArtillarySmokePos. A vector is three points, Float vec[3], X, Y, Z. You're only changing X and Y (Z is vertical) which is why they may seem to be landing in one line.

Vertical being in the air correct? The point is for the smoke to be on the ground.

X and Y represents you moving around on a flat plane. Z represents you crouching or jumping. It's vertical like the height of a building. If you never change Z, then everything will spawn at the same height.

[hmmmmm]

Z (3rd index) is the height, but in your code you set up ArtillarySmokePos2:

PHP Code:

ArtillarySmokePos2[0] += GetRandomFloat(125.0, 250.0); //Done
ArtillarySmokePos2[1] -= GetRandomFloat(125.0, 250.0); //Done
TeleportEntity(ArtillarySmoke2, ArtillarySmokePos2, NULL_VECTOR, NULL_VECTOR); 


After that you only change the X component of ArtillarySmokePos2:

PHP Code:

ArtillarySmokePos2[0] -= GetRandomFloat(250.0, 500.0); //Done 


And then you teleport ArtillarySmoke3 to ArtillarySmokePos2:

PHP Code:

TeleportEntity(ArtillarySmoke3, ArtillarySmokePos2, NULL_VECTOR, NULL_VECTOR); 


without changing the Y component of ArtillarySmokePos2, meaning that ArtillarySmoke2 and ArtillarySmoke3 have the same Y position. Again, the way you've done this is confusing and I would recommend just doing a loop like the example I showed above. If you're still having trouble provide more context to your issue or:

I'd also recommend doing some debug prints to see what positions they all end up at and whats happening at every stage of the code.
