Global Entitys?

[SpiderPig]

I'm using C++ 2010, and I'm trying to make a function to rotate a car door, but the door model is loaded in the "main" function so that makes it local only to that function right?

How do I get other functions to recognize it too?

I've tried Initializing, setting up the graphics and loading the door before "main", but it doesn't work...

Any suggestions?

(I'm rather new to both C++ and LeadWerks)

 

Thanks

[carlb]

would not use 2010 yet, there still a few bug in it

stick with the older version

[SpiderPig]

Ahhh, really?

That'd explain a few problems...

Thanks carlb!

 

So is this global Entity problem only with 2010 you think?

Or its got nothing to do with it?

Probably nothing to do w/ it. Post some code, too hard to diagnose just guessing what you have.

Here's The code I'm using,

Everything else works fine. It just doesn't know what 'TailGate' is,

 

#include "engine.h"

void UdateTailGate(void);
int TailGateAngle=0;
int TailGateStatus=0;

int main(int argc,char** argv)
{

Initialize();
Graphics(1024,768);
CreateWorld();


TEntity MainCam=CreateCamera();
PositionEntity(MainCam,Vec3(0,6,-7));
RotateEntity(MainCam,Vec3(30,0,0));


TLight MainLight=CreateSpotLight(20.0);
TLight MainLight2=CreateSpotLight(20.0);
PositionEntity(MainLight,Vec3(0,12,6));
PositionEntity(MainLight2,Vec3(0,12,-6));

SetShadowmapSize(MainLight,2000);
SetShadowmapSize(MainLight2,2000);
RotateEntity(MainLight,Vec3(90,0,0));
RotateEntity(MainLight2,Vec3(90,0,0));


TEntity Floor=CreatePlane();
ScaleEntity(Floor,Vec3(10,1,10));
TEntity Car=LoadModel("JeepMain.gmf");

TEntity Bonnet=LoadModel("Bonnet.gmf");
PositionEntity(Bonnet,Vec3(0.012,3.177,-1.297));
EntityParent(Bonnet,Car);

int BonnetAngle=0;
int BonnetStatus=0;//0-closed,1-open,2-opening,3-closeing



TEntity TailGate=LoadModel("TailGate.gmf");
PositionEntity(TailGate,Vec3(-1.105,2.249,4.578));
EntityParent(TailGate,Car);


TEntity SpareWheel=LoadModel("Wheel.gmf");
PositionEntity(SpareWheel,Vec3(0,2.293,5));
EntityParent(SpareWheel,TailGate);



TEntity LeftDoor=LoadModel("LeftDoor.gmf");
PositionEntity(LeftDoor,Vec3(1.975,2.669,-0.618));
EntityParent(LeftDoor,Car);





TBuffer Buffer=CreateBuffer(1024,768,BUFFER_COLOR|BUFFER_DEPTH|BUFFER_NORMAL);//buffer for teh lights
float CarAng=0.0;



while(!KeyHit(KEY_ESCAPE))
{

if(KeyHit(KEY_==1)
{
if(BonnetStatus==0)
{
BonnetStatus=2;
}
else
{
if(BonnetStatus==1)
{
BonnetStatus=3;
}
}



}

if(BonnetStatus==2)
{
if(BonnetAngle<60)
{
BonnetAngle++;
RotateEntity(Bonnet,Vec3(BonnetAngle,0,0));
}
else
{
BonnetStatus=1;//open
}
}

if(BonnetStatus==3)
{
if(BonnetAngle>0)
{
BonnetAngle--;
RotateEntity(Bonnet,Vec3(BonnetAngle,0,0));
}
else
{
BonnetStatus=0;//closed
}
}


UdateTailGate();



RotateEntity(Car,Vec3(0,CarAng,0));
CarAng=CarAng-0.2;

UpdateWorld(1);
SetBuffer(Buffer);


RenderWorld(RENDER_ALL);
SetBuffer(BackBuffer());
RenderLights(Buffer);
SetBuffer(BackBuffer());


Flip(1);

}

Terminate();
return 0;

}





void UdateTailGate(void)
{

if(KeyHit(KEY_T)==1)
{
if(TailGateStatus==0)
{
TailGateStatus=2;
}
else
{
if(TailGateStatus==1)
{
TailGateStatus=3;
}
}
}


if(TailGateStatus==2)
{
if(TailGateAngle<100)
{
TailGateAngle++;
RotateEntity(TailGate,Vec3(0,TailGateAngle,0));//Tailgate is an undeclared Identifier
}
else
{
TailGateStatus=1;//open
}
}

if(TailGateStatus==3)
{
if(TailGateAngle>0)
{
TailGateAngle--;
RotateEntity(TailGate,Vec3(0,TailGateAngle,0));
}
else
{
TailGateStatus=0;//closed
}
}
};

You need to declare the global variables before the functions which use them, and please use the code tag in the forum when you paste code:

int TailGateAngle=0;
int TailGateStatus=0;
void UdateTailGate(void);

[SpiderPig]

You know, just as I posted that I thought, "I know how to fix that,"

At the beginning of the code (before 'main') i added : TEntity Tailgate;

 

Then when I load the model instead of TEntity TailGate=LoadModel("TailGate.gmf");

I just used : TailGate=LoadModel("TailGate.gmf");!!!!

And it works fine....(I feel stupid)

Thanks though!!

[SpiderPig]

Ok, I'll declare them before the function, Thanks
