Array of Blips

[cmPLX 1]

Evening,

 

Forgive me for my lack of knowledge on this subject, coming from Self Taught programming. Trying to create an array of Blips for my Suspects. How would I go about initializing this Array so it does not return a NULL value when I want to use them?

 

Thanks,

Create my Blip Array

private Blip[] SuspectBlips;

Then when I create the Peds, I'm using this.

SuspectBlips[i] = this.drivebys[i].AttachBlip();

Use a List, not an array. Lists are meant to have things added to them all the time. 

 

The way I'd do it is something like this:

 

List<Blip> blips = new List<Blip>();

for(var driveby in drivebys)
{
  Blip b = driveby.AttachBlip();
  b.Color = whatever;
  b.Name = whatever;
  blips.Add(b);
}

Parks is right, in most cases when you don't know the actual runtime lenght of an array you should use another data structure. Your example doesn't work because you did not initialize your array = it doesn't have any values.

Also, it seems to me you should replace AttachBlip() with a Blip constructor and pass an entity to it.

It should look this way:

private Blip[] SuspectBlips = new Blip[1];
SuspectBlips[0] = new Blip(drivebys[i]);

Array is fine when you know the lenght of your collection and/or write high performance code.

Thanks PNWParksFan and LtFlash, this helped me a lot. I only have a max length of 3 for the array due to limited passenger seats.
