I always get problems with rez higher than 1024x768 on my SAM ...
More to this, it's not impossible to change display resolution during game with menus ...

@Gazelle
ok.

Now I understand how the pointer in struc works.

Thank you Gazelle.

When compiling, I also get some errors on things I'read here for example :

definition :


typedef struct Object3DType{

 ...

 };


Object3DType *Allocate3DObject( int ObjectID ){

  ...

 }

Basic3D.c:48: error: expeted '=', ',', ';', 'asm' or '__attribute__' before '*' token

and


void Free3DObject( Object3DType *OldObject ){

 ...

 }

Basic3D.c:71: error: expected ')' before '*' token

Why ? I use exactly what was adviced to me here in this post ...

Kindest Regards,
Freddix

I encounter another problem with structures.
I've made this with the book help :


struct Basic3DStructType{

  int *LastCreatedObject;

 };

struct Basic3DStructType Basic3D;



struct Object3DType{

  int *PreviousObject, *NextObject;

 };



void BASIC3D_Destructor( void ){

  struct ObjectType *NewObject = Basic3D.LastCreatedObject;

   struct Object3DType *NextToDelete = NewObject.PreviousObject;

 }

I've removed other lines to just show what is wrong ...
I get an error on this line :
Quote:

struct Object3DType *NextToDelete = NewObject.PreviousObject;

BAsic3D.c:64: error: request for member 'PreviousObject' in something not a structure or union

Why ?

I tried to change struc to these :
Quote:

struct Object3DType{
int PreviousObject, NextObject;
};

Same Result ...

Any info ?

Thank you.

A friend just sent me an e-mail explaining linked-list too.
now I understand what I must do to handle objects dynamically.

Thank you all.

@xeron
Do you think that handling the list per ranges can be good ?

For example :
Default is defined with 512 entries,
If more than 512, directly re-allocate 1024 entries,
if more than 1024, directly re-allocate 1536 entries,
if more than 1536, directly re-allocate to 2048 entries,
etc ...

Good idea ?

@salass00
It's what I supposed .... but wasn't sure ...
Thank you.

If I'm not wrong, all this should be correct :


typedef struct{

  BOOL Exist;

  int Type;

  BOOL Hidden, Culling, Transparency, WireFrame, Fog, Ambient, Lights, Filtering;

  float XPos, YPos, YPos;

  float XRot, YRot, ZRot;

  float XScale, YScale, ZScale;

  float RGBRed, RGBGreen, RGBBlue;

 }Object3DType;



static Object3DType *Allocate3DObject( void );

static void Free3DObject( Object3DType *OldObject );



Object3DType *Allocate3DObject( void ){

  Object3DType *NewObject = NULL;

  NewObject = IExec -> AllocVecTags( sizeof( Object3DType ), TAG_DONE );

  if ( !NewObject ){

    return NULL;

   }

  return NewObject;

 }



void Free3DObject( Object3DType *OldObject ){

  if ( obj != NULL ){

    IExec -> FreeVec( OldObject );

   }

 }

Right ?

GCC, resize dynamically an array. Possible ?

Posted on: 2009/2/25 19:27 #614

Hi All,

I've checked my entire C book concerning arrays and I did find nothing related to resizing an array.

Is it possible to directly change the size of an array inside a program ?

(post that kind of questions will probably makes me be considered as a noob ... it's a risk ... but progress nevers happen without risks ;) )

@xeron
Thank you for this small function.

I imagine that if I want to delete this object from memory, I'll have to do something like this :


*FreeObject( NewObjectType ){

  if ( NewObjectType <> 0 ){

    IExec->FreeVec( NewObjectType );

   }

 }

Am I wrong ?

GCC, Dynamic structure creation method ?

Posted on: 2009/2/25 18:29 #616

Quite a regular

Hi,

In fact, I want to create dynamically objects that uses a structure.

Imagine a structure like this one :


typedef struct{

  BOOL Exist;

  float XPos, YPos, ZPos;

  float XRot, YRot, ZRot;

  float FOV;

  BOOL Backdrop;

  float RangeNear, RangeFar;

  float Left, Top, Right, Bottom;

 }ObjectType;

I want to have a function in my program that allocate a small memory for an object that'll use this structure and, the function must return the pointer to the freshly created object structure.

I'm not enough skilled in C to imagine how to do this.
Any one got an idea about this ?

Thank you.

Kindest Regards,
Freddix
