Figured it should be posted here -_-

+ Code Snippet

function RenderVectorModel(Model as VectorMap, ParamCount, X, Y, Angle)
   for I = 0 to (ParamCount - 1)
      ink rgb(255,0,0),0
      line X, Y, X - (cos(Angle) * Model(I).Distance), Y - (sin(Angle) * Model(I).Distance
      next I
   endfunction

When called like this:

+ Code Snippet

RenderVectorModel(TestModel,1, 320,240, Angle)

it gives the error:

Quote: "Variable 'Model' does not exist on line 24."

Which is the the line where the LINE function sits..

This is how TestModel is created:

+ Code Snippet

dim TestModel(2) as VectorMap

Any ideas? I think I got a little too much C++ in my blood

If I've got it all wrong.. is there a straight-foward way to use dynamic arrays? I was hoping I wouldn't have to go memblock crazy again

Crap..

Well I found an effective way to crash DBPro

+ Code Snippet

function RenderVectorModel(dim Model() as VectorMap, ParamCount, X, Y, Angle)

You can't pass arrays to/from functions like that.

You can do some nasty stuff with my Array plug-in that can simulate it, but I really wouldn't advise it.

Also in that case the TestModel array is global so can be referenced inside the array. If you want it to work on a different array depending on where it's called (Which i've done a couple of times) i'd do something like this:

+ Code Snippet

#constant modelsMain 1
#constant modelsTest 2

#constant maxModels 2
global dim TestModel(maxModels) as VectorMap
global dim MainModel(maxModels) as VectorMap

function RenderVectorModel(modelFlag as integer, ParamCount, X, Y, Angle)
   local modelDist as integer

   for I = 0 to (ParamCount - 1)
      ink rgb(255,0,0),0
      select modelFlag
         case modelsMain
            modelDist=ModelsMain(I).Distance
         endcase
         case modelsTest
            modelDist=ModelsTest(I).Distance
         endcase
      endselect
      line X, Y, X - (cos(Angle) * modelDist), Y - (sin(Angle) * modelDist
   next I
endfunction
