Help me convert this starfield script please.

EDIT, used something else in the end.

 

I do have a 'Resources' directory with the textures in waiting to load btw.

 

I should email the chap... is he instantiating those stars or drawing them via draw-texture...I simply don't know, I'll have to experiment

 

I think the error is caused because the variable random is not getting set correctly. I noticed the only place in the given code it is called is OnStart which is notoriously buggy in Unity try moving the OnStart code to OnEnable and see if that helps the issue.

 

What do you mean "Buggy"? OnStart isn't even a unity function anyway, it's just Start()

 

Your console output doesn't seem to be matching up with your script line numbers, and the errors look strange... Did you abbreviate them or something? Looks like it should be a Vector, but the output is cut off. Knowing that full line would help.

Null Reference Exception means you're trying to access a variable that hasn't been set. The following lines should point you to where that's occurring, but that doesn't seem to jive with what I see in your script at those lines.

Edit: Just saw your comment on the code creator's post. SpriteBatch is the XNA way of drawing your 2D assets as a batch (combined render calls) that doesn't exist as-is in Unity. I haven't done anything with 2D in Unity, so I don't know what the equivalent would be, but it may be worth reading about XNA and SpriteBatch to see how you can apply the principles of what it does to Unity.

 

Got ya, I didn't know what XNA was, slightly better informed now, there is more information HERE about this particular call but anyway I'll have to convert it seemingly, I'll have a crack at it, cheers
