Lets say you have public fixed int pointx[300]; How do you pass it via function?

One more small question before I come back later. Lets say you have public fixed int pointx[300]; //in your IComponentData and you wanted to pass pointX[300] through a function/method. I can't find the exact syntax. Any help?

 

Pass the ICommontentData.

 

I want to pass to IComponentData not from.

Or generally to use in C#.

Do I pass by a * or something?

 

You know, now that I think of it, I don't; have to pass an array. I can just call a function 300 times passing an integer one at a time and reconstruct the array.

I just thought there was an easy way to pass an array. I guess not.

 

I don't get it.

If you have an IComponentData that encapsulate the fixed array, just create the IComponentData, assign the fixed array and then pass the IComponentData.

Calling 300 time a service an reconstructing the array after that seem like a terrible idea.

 

You mean by "ref" in this case?

 

You guys seem very very confused, and maybe it is my bad communication.

Ignore IComponentData, forget DOTS even existed, and we're just C#.

Lets say I had a class that had an array.

public fixed int pointx[300];


and this class had a method:

public void assign PointXValue( ????? )
{

}

What would the ???? be to accept passing an identical 'public fixed int pointx[300]' from elsewhere?

 

You pass it by pointer

Code (CSharp):

1. public unsafe struct TestStruct
2. {
3.     public fixed int point[300];
4.  
5.     public void Pass()
6.     {
7.         fixed (int* p = point)
8.         {
9.             Method(p);
10.         }
11.     }
12.  
13.     public static void Method(int* b)
14.     {
15.  
16.     }
17. }

 

Tanks super bro terle dude. Party on Garth.

 

Wow, I feel doubly blessed! I actually forgot this, then found my own post in the search! I also surprised myself with a joke not knowing it was me. I was like,"Who is this awesome dude with Wayne's World References." Wait, the turtle dude was a guy who helped me before. Wow the awesome guy I didn't know is me! But Tertle is way more awesomer!

 

In the future (>=2021.2) you can also use Span<T> Then you don't have to mess with pointers and can also be used outside of unsafe context.
