Sprite error

Martin

We're going to need to see far more than that! there's nothing wrong with that line alone. Unless it IS alone and there's no more :D

for I = 0 to len( rocks ) loop
      n = random( 4 )
      rocks[i].spr = createSprite()
      setSpriteImage( rocks[i].spr, rockImgs[n] )
     rocks[i].pos = { screen.x + random( screen.x * 2 ), random( screen.y ) } 
     rocks[i].vel = { random( -screen.x / 5 ), random( 32 ) - 16 }
    setSpriteAnimation( rocks[i].spr, 0, 39, 10 )
    setSpriteLocation( rocks[i].spr, rocks[i].pos )
Repeat

Some things that might be worth checking:

is rocksImgs indeed an array containing 3 images?
Is the variable screen indeed a struct with the properties x and y?
what does the rocks array contain before going into this loop? Do the structs in the rocks array already have the properties spr, pos and vel?

From the code snippet that's published above there are loads of variables being used that don't exist. So without further info, I would indeed expect to see an invalid variable access error. But I guess you have other code that you're not showing us.

It is working for me but I had to assume the variable/struct definitions were something like this:

struct rock
  var spr
  int pos
  int vel
endstruct

rock rocks[10]

BTW you don't need to create your own position and velocity properties as sprites already have them!

Is rocks a struct, or is it meant to just be an array of sprites? If it's the latter changing rocks[i].spr to just rocks[i] would probably fix it.

Martin

But we're all just guessing....

I found out why it was giving me an error. I misspelled a word in the code and I forgot a ","
