maybe i should add that this line is in a class that was used as a normal variable before, but i tried to use it as a pointer now.
So this line is in
void MD3Model::RenderItp(int currframe, int nextframe, float pct)
Before i changed it, this class was used as following:
MD3Model lower, upper, head;
Now i use it as following:
MD3Model *lower, *upper, *head;
lower = new MD3Model(/*constuctor arguments*/);upper = new MD3Model(/*constuctor arguments*/);head = new MD3Model(/*constuctor arguments*/);Quote:

yeah thought so too, but i have done that.
Additionally i have a md3character (thats the class using the 3 md3models), that creates these md3models and can render them without errors.
But when i make a new md3character and give the addresses of these 3 md3models to it, the render crashes as i said above.
MD3Character cha;Md3Character *player; cha.Initialize(d3d.pdevice); cha.LoadPlayer("klesk\\","red"); player = new MD3Character(); player->Initialize(d3d.pdevice); player->SetPlayer("klesk\\",cha.lower, cha.upper, cha.head);void MD3Character::LoadPlayer(char *path, char *skin){ char l_mpath[1024], u_mpath[1024], h_mpath[1024]; // model (lower, upper, head) char l_spath[1024], u_spath[1024], h_spath[1024]; // skin char a_path[1024]; // animation sprintf(l_mpath, "%s\\lower.md3", path); sprintf(u_mpath, "%s\\upper.md3", path); sprintf(h_mpath, "%s\\head.md3", path); sprintf(l_spath, "%s\\lower_%s.skin", path, skin); sprintf(u_spath, "%s\\upper_%s.skin", path, skin); sprintf(h_spath, "%s\\head_%s.skin", path, skin); sprintf(a_path, "%s\\animation.cfg", path); lower = new MD3Model(); upper = new MD3Model(); head = new MD3Model(); // Load Model lower->LoadModel(l_mpath); // lower body upper->LoadModel(u_mpath); // upper body head->LoadModel(h_mpath); // head lower->Initialize(device); upper->Initialize(device); head->Initialize(device); // Load Skins lower->LoadSkin(l_spath, path); upper->LoadSkin(u_spath, path); head->LoadSkin(h_spath, path); LoadAnim(a_path); lower->LinkModel("tag_torso", upper); upper->LinkModel("tag_head", head); SetAnimation(LEGS_IDLE); SetAnimation(TORSO_STAND); Rotation.x = 0; Rotation.y = 0; Rotation.z = 0; Initialized = true;}void MD3Character::SetPlayer(char *path, MD3Model *lower, MD3Model *upper, MD3Model *head){ char a_path[1024]; sprintf(a_path, "%s\\animation.cfg", path); this->lower = lower; this->upper = upper; this->head = head; LoadAnim(a_path); //lower->LinkModel("tag_torso", upper); //upper->LinkModel("tag_head", head); SetAnimation(LEGS_IDLE); SetAnimation(TORSO_STAND); Rotation.x = 0; Rotation.y = 0; Rotation.z = 0; Initialized = true;}void MD3Character::LoadPlayer(char *path, char *skin){ char l_mpath[1024], u_mpath[1024], h_mpath[1024]; // model (lower, upper, head) char l_spath[1024], u_spath[1024], h_spath[1024]; // skin char a_path[1024]; // animation sprintf(l_mpath, "%s\\lower.md3", path); sprintf(u_mpath, "%s\\upper.md3", path); sprintf(h_mpath, "%s\\head.md3", path); sprintf(l_spath, "%s\\lower_%s.skin", path, skin); sprintf(u_spath, "%s\\upper_%s.skin", path, skin); sprintf(h_spath, "%s\\head_%s.skin", path, skin); sprintf(a_path, "%s\\animation.cfg", path); // and it goes on!Quote:

it is a scope problem like I said, just before Rip-of ripped into me ... and while they do the same thing they way the compiler goes about doing it is slightly different thats all I said.

I then stated it prolly scope. you have a function void MD3Character::LoadPlayer(char *path, char *skin)
in this function the 3 models are create lower, upper, head all get newed thats fine .. thing is they lost scopre once that function is dead. what need to do is have the models pointers waiting before the call and passed in as variables. void MD3Character::LoadPlayer(char *path, char *skin, model* lower, model* upper, model* head )
this way when your done doing the new, its puts it in the ones that have a greater scope. If you then have your entire game ran from inside a single clss having the 3 model*'s as part of that class will keep them for the duration. ...

Sorry if my msg doesnt come accross well ... Im practically falling asleep ... TSCrusader has anyquestions he can se the messaging service to ask and will get a direct answer with in no longer then 2 days

another simple question:
how can i pass one element of an array of pointers so that the function can modify this?
MD3Model** models;
modelpool = new MD3Model*[10];
then pass models[0] ie to a function so that this function can fill this pointer.
void FillModel( MD3Model* ){ //stuff}void foo(){ MD3Model** modelpool ; modelpool = new MD3Model*[10]; for( int i = 0 ; i < 10 ; ++i ) { FillModel( modelpool ); }}void FillModel( MD3Model* ){ //stuff}void foo(){ vector<MD3Model*> modelpool(10); for( int i = 0 ; i < modelpool.size() ; ++i ) { FillModel( modelpool ); }}This topic has been locked by a moderator.
