arrays in script

#1 Arrays in script work like you would normally do them in C/C++ ie:

%bla[0] = "one;
%bla[1] = "two";

echo(%bla[0]);
echo(%bla[1]);

Alternatively I think this works as well(not sure though):

%bla[0] = "one";
%bla[1] = "two";

echo(%bla0);
echo(%bla1);

I think both ways work. So are you absolutely sure your code is correct?

#2 Hm, guess part of the problem is

void TGEConSequence::initPersistFields()
{
        ...
	addField("TConText", TypeString, Offset(mTConText, TGEConSequence));

but how do I expose the my array to the scripting engine correctly...?
I found TypeEnum, but if I use it instead, it crashes the engine... hmmmmm....

#3 Okay,
so here is all the code related to this text array... maybe I got an error somewhere and I'm too blind to see it...

const char* mTConText[MaxSequences];
	void setTConText(const char* Text, U32 index);
	const char* getTConText(U32 index);

void TGEConSequence::setTConText(const char* Text, U32 index){
	mTConText[index] = StringTable->insert(Text);
}
const char* TGEConSequence::getTConText(U32 index){
	return mTConText[index];
}
static void csetTConText(SimObject * obj, S32, const char ** argv)
{
	TGEConSequence *seq = static_cast<TGEConSequence*>(obj);
	if (!seq) return;
	seq->setTConText(argv[2], dAtoi(argv[3]));
}

static const char * cgetTConText(SimObject *obj, S32, const char** argv)
{
	TGEConSequence *seq = static_cast<TGEConSequence*>(obj);

   const char* text = seq->getTConText(dAtoi(argv[2]));
   return(text);
}
void TGEConSequence::initPersistFields()
{
	Parent::initPersistFields();
	addField("TConText", TypeString, Offset(mTConText, TGEConSequence));
}
void TGEConSequence::consoleInit()
{
	Con::addCommand("TGEConSequence", "setTConText", csetTConText, 
        "tConSeq.setTConText(text, index)", 4, 4);
	Con::addCommand("TGEConSequence", "getTConText", cgetTConText, 
        "tConSeq.getTConText(index)", 3, 3);
}

Hm, that's pretty much it concerning this text array ... anybody found any errors?

#4 TypeEnum requires a static array.

Anyways, that's not what you want.

This is:

// Instead of this:
void TGEConSequence::initPersistFields()
{
        ...
	addField("TConText", TypeString, Offset(mTConText, TGEConSequence));

// Put this:
void TGEConSequence::initPersistFields()
{
        ...
	addField("TConText", TypeString, Offset(mTConText, TGEConSequence),iNumElements);

// Here, iNumElements is the number of elements in the mTConText array

#5 Hey, thanks a lot - that did it!!! But why?
Is this appended number telling the scripting engine that this "TypeString" is actually an array?
Anyhow, now it works! :-) Back to work...
And thanks again for the quick help!!

#6 Little addon... ;) Is it possible to get the length of the current array in script? like "TConText.length()" or "TConText.size()" or something? Or do I have to use my own counter for this?

#7 Hi all,

I know this thread has been dead for a very long time but it's the closest topic I found to my question so I thought I'd try following up here. Can you use a Vector (defined in tVector.h) similarly to how you can use an array? Also, do arrays have to be static? In the example above, is iNumElements static or can the array grow? Anyway, back to my Vector based question...

I've created a struct called VEEQuad which takes 4 VEE_Vector3 types to create a plane. For this discussion, consider VEE_Vector3 to be a Point3F. So my struct is...

struct VEEQuad { VEE_Vector3 a,b,c,d; };

Then I'm defining my ConsoleType...

DefineConsoleType( TypeVEEQuad )

ConsoleType( VEEQuad, TypeVEEQuad, sizeof(VEEQuad) )

ConsoleGetType( TypeVEEQuad )
{
	VEEQuad *qd = (VEEQuad *) dptr;
	char* returnBuffer = Con::getReturnBuffer(256);
	dSprintf(returnBuffer, 256, "{ \"%g %g %g\", \"%g %g %g\", \"%g %g %g\", \"%g %g %g\" }", qd->a.x, qd->a.y, qd->a.z, qd->b.x, qd->b.y, qd->b.z, qd->c.x, qd->c.y, qd->c.z, qd->d.x, qd->d.y, qd->d.z);
	return returnBuffer;
}

ConsoleSetType( TypeVEEQuad )
{
   if(argc == 4)
		{
		dSscanf(argv[0], "%g %g %g", &((VEEQuad *) dptr)->a.x, &((VEEQuad *) dptr)->a.y, &((VEEQuad *) dptr)->a.z);
		dSscanf(argv[1], "%g %g %g", &((VEEQuad *) dptr)->b.x, &((VEEQuad *) dptr)->b.y, &((VEEQuad *) dptr)->b.z);
	    dSscanf(argv[2], "%g %g %g", &((VEEQuad *) dptr)->c.x, &((VEEQuad *) dptr)->c.y, &((VEEQuad *) dptr)->c.z);
		dSscanf(argv[3], "%g %g %g", &((VEEQuad *) dptr)->d.x, &((VEEQuad *) dptr)->d.y, &((VEEQuad *) dptr)->d.z);
		}
   else
      Con::printf("VEEQuad must be set as { \"x y z\", \"x y z\", \"x y z\", \"x y z\" }");
}

Then I'm setting up my vector...

Vector<VEEQuad*>	mQuadList;

And finally was trying to use it in my initPersistFields...

addField("QuadList", TypeVEEQuad, Offset(mQuadList, VEECollision), mQuadList.size);

I am getting the following error: invalid use of member 'VEECollision::mQuadList' in static member function

So, I could have any number of mistakes in here (and welcome anyone who finds them to point them out) but if this isn't even doable, I'd like to know that too.

Thanks,

Ben
