How would I go about checking if all parts of a Vector[3] are valid? I am guessing the proper description would be NULL_VECTOR? I have a script I am trying to debug with this error in my console:

Bad SetLocalOrigin(nan,nan,nan) on info_particle_system

Presumably, this happens when I am calling

PHP Code:

TeleportEntity(iEntity, fOrigin, NULL_VECTOR, NULL_VECTOR) 


I'm sure it's simple, just need to make sure I am doing it right, thanks all!

afaik there's no check for valid vectors.

send more code ( ͡° ͜ʖ ͡°), easier to help

Surely there is a simple way to do this. Something really simply just to check to see if a vector is valid and not NULL, etc. If I were to make a stock, something like this:

PHP Code:

stock bool IsValidVector(float fVector[3])
{
    /// code to check if 'fVector' IS VALID (NOT NULL, EMPTY, ETC)
}

Maybe you could show us how you're computing "fOrigin"?

Any vector, just check if it actually has a value in it. That's all, really simple. I'm not sure what else I could describe here.

Here is an example

PHP Code:

stock void SpawnEntity(int client) {
    
    float fOrigin[3];
    
    GetClientAbsOrigin(client, fOrigin);

    int iEntity = CreateEntityByName("prop_physics");

    if(IsValidEntity()) {
        GetEntPropVector(iEntity, Prop_Send, "m_vecOrigin", fOrigin);

        TeleportEntity(iEntity, fOrigin, NULL_VECTOR, NULL_VECTOR) 
        // Sometimes 'fPosition' is getting console errors
        // ==> Bad SetLocalOrigin(nan,nan,nan) on prop_physics
    }
}

Well first of all, you need to spawn the prop before getting its location (unless that's just part of your example?), also you're getting the location before the prop really has an origin. So you need to teleport the entity/set its origin before retrieving its location.

For the stock, I'm not sure but I presume null vectors were to be 0.00000 for x, y, and z. So maybe

PHP Code:

stock bool IsValidVector(float fVec[3])
{
    int iCheck;
    
    for (int i = 0; i < 3; ++i)
    {
        if (fVec[i] == 0.0000)
            ++iCheck;
        else 
            break;
    }
    return view_as<bool>(iCheck != 3);
}

Thanks for your reply, yes that was just a bare and stripped down (non-functional) example of the actual code. Just looking to see if a vector (regardless of how it was assigned values) is valid and not NaN or NULL. Nothing fancy. I will give your code a shot this weekend, much appreciated.

Thanks for everyone's replies.

If the problem is just that the values are NaN, then you can check by comparing the value to itself. NaN always compares as inequal, even to itself.

It's possible for {0, 0, 0} to be a valid location in a map. It's unlikely that anything will be exactly at that spot unless it was intentionally spawned there (or someone forgot to set coordinates).

Thanks for you input you're absolutely right, it makes sense now how to do this. Here is the simple solution I came up with to check for invalid NaN vectors if anyone wants it. The NaN reference is in accordance to IEEE standards, which looks odd, but works.

Thanks everyone for your help

PHP Code:

stock bool IsValidVector(float fVector[3])
{
    // NaN Check
    if(fVector[0] != fVector[0] || fVector[1] != fVector[1] || fVector[2] != fVector[2])
    { return false; }

    // Valid Vector
    return true;
}
