Linepick point2

[ParaToxic]

Hello,i try to make a bullet class with Raycasting.I made a point1 at the player position and point2 like:

point2=Vec3(0,0,30);
point2=TFormVector(point2,cam,NULL);

LinePick(&pick,point1,point2);

 

this,but when i check the values of point2,its wrong.

How can i solve this problem?

 

Thank you

How is it wrong?

[ParaToxic]

So i have a little example.Maybe somebody can told me why it is wrong.

 

#include "engine.h"
int main(int argc, char** argv)
{
Initialize();

Graphics(800,600);

TCamera cam=CreateCamera();
PositionEntity(cam,Vec3(0,2,-10));
Collisions(1,2,true);

TModel scene=LoadModel("scene.gmf");

EntityType(scene,2);

TLight light=CreatePointLight();
PositionEntity(light,Vec3(0,5,0));

TBuffer buffer=CreateBuffer(800,600,BUFFER_COLOR|BUFFER_DEPTH|BUFFER_NORMAL);

TController player=CreateController();
SetBodyMass(player,6);
EntityType(player,1);



TVec3 point1=Vec3(0,0,0);
TVec3 point2=Vec3(0,0,0);
TVec3 a=Vec3(0,0,0);
TVec3 b=Vec3(0,0,0);
TPick pick;


float move=0.0;
float strafe=0.0;
TVec3 camrotation=Vec3(0);
float mx=0;
float my=0;
HideMouse();
MoveMouse(GraphicsWidth()/2,GraphicsHeight()/2);

while(!KeyHit(KEY_ESCAPE)) {

mx=Curve(MouseX()-GraphicsWidth()/2,mx,6);
my=Curve(MouseY()-GraphicsHeight()/2,my,6);
MoveMouse(GraphicsWidth()/2,GraphicsHeight()/2);
camrotation.X=camrotation.X+my/10.0;
camrotation.Y=camrotation.Y-mx/10.0;
RotateEntity(cam,camrotation);

move=KeyDown(KEY_W)-KeyDown(KEY_S);
strafe=KeyDown(KEY_D)-KeyDown(KEY_A);

UpdateController(player,camrotation.Y,move,strafe);

UpdateWorld();

TVec3 playerpos=EntityPosition(player);
TVec3 camerapos=EntityPosition(cam);
camerapos.Y=Curve(playerpos.Y+1.75,camerapos.Y,2.0);
camerapos=Vec3(playerpos.X,camerapos.Y,playerpos.Z);
PositionEntity(cam,camerapos);


point1=EntityPosition(cam);
point2=Vec3(0,0,4);
point2=TFormVector(point2,cam,0);

if(LinePick(&pick,point1,point2,0,0))
{
        a=CameraUnproject(cam,point1);
        b=CameraUnproject(cam,Vec3(pick.X,pick.Y,pick.Z));
}


SetBuffer(buffer);
RenderWorld();
SetBuffer(BackBuffer());
RenderLights(buffer);

DrawLine(a.X,a.Y,b.X,a.Y);
Flip();
}
return Terminate();
}

 

Thank you for advanced

As far as I know you don't need to be transforming that vector into camera space. It is technically already in camera space.
