Physics rare behavior

[DarthRaff]

Hello,

 

Can someone, please, copy that code (i assume you have the SDK oildrum model)and do:

First execute it and try collide with some object.

Then delete oildrum2 from code,execute and try collide with some object.

Any difference? please, tell me. THankyou

 

the code:

#include <math.h>
#include <string>
#include <vector>

Please,

 

I have problems with collisions and don't know how to solve it. Can someone try and tell me, please. Thankyou.

[Marleys Ghost]

Please,

 

I have problems with collisions and don't know how to solve it. Can someone try and tell me, please. Thankyou.

 

 

What problem?

[DarthRaff]

hi,

 

The problem is that if i put a cube with collision created by code or two or three, the collisions goes perfect, but if i try to put more than one oildrums or another gmf file the collisions fails because if you collide with an object it goes away too fast or keeps rotating around the character controller, or another malfunction. If there is just one oildrum or just one monster created by me the collisions goes perfect but if i try to put two or more of the gmf objects in the same scene the collisions fails i don't know way. all updated and copied to the right place because the collisions of objects created by code works perfect just fails more than one gmf in the same scene.

 

The code above is for best understanding of the problem. If you coul'd try it you will see.

the first fails and then if you delete oildrum2 from the code then goes perfect with one cube create by code and one oildrum.gmf.

[Marleys Ghost]

Well first of all try changing:

 

UpdateController(player,camrotation.Y,move,strafe,jump,10000);

 

To something like:

 

UpdateController(player,camrotation.Y,move*3,strafe*3,jump,500);

 

See if there is an improvement.

[Marleys Ghost]

If you want others to run your code you would also need to post the monsterfuncs.h

[DarthRaff]

You right, sorry, but when i try to attach something have that error:

 

"Error You aren't permitted to upload this kind of file".

 

please tell me how to attach files.

 

change to 500 or 100 don't solve the problem, thankyou.

[Marleys Ghost]

Simply post monsterfuncs.h as code the same as you did for the main prog.

[Marleys Ghost]

Also what scene.gmf? is it the one for the controller tutorial?

[DarthRaff]

Yes is the same of the character controller. And here is monsterfuncs.h:

void SlowPointEnt(TEntity ent1,TEntity ent2,float speed)
{
TVec3 ent1pos=EntityPosition(ent1);
TVec3 ent1rot=EntityRotation(ent1,0);
TVec3 ent2pos=EntityPosition(ent2);
float dx=0.0;
float dy=0.0;
float dz=0.0;
float rz=0.0;
//float speed=1.0;
dx=ent1pos.X-ent2pos.X; 
dy=ent1pos.Y-ent2pos.Y; 
dz=ent1pos.Z-ent2pos.Z;
rz=ent1rot.Z;
return AlignToVector(ent1,Vec3(dx,rz,dz),3,speed);
}

void AnimeEntitySeq(TEntity ent,float startframe=0.0f, float finalframe=1.0f, float vel=1.0f, float partitiontime=100.0f)
{
float frame;
//framebegin=startframe;
//frameend=finalframe;
//Animate(ent,frame,1,0,1);
frame=(AppTime()*vel)/partitiontime;
//frame=fmodf(frame,frameend-framebegin)+framebegin;
frame=fmodf(frame,finalframe-startframe)+startframe;
Animate(ent,frame,1,0,1);
}

[Marleys Ghost]

change to 500 or 100 don't solve the problem, thankyou.

 

 

did you just change the acceleration value or did you change the whole line?

 

UpdateController(player,camrotation.Y,move*3,strafe*3,jump,500);

[DarthRaff]

hey, i just changed acceleration, sorry, now works perfect. Thankyou very much Marleys Ghost, but why multiply move and strafe per 3?

[Marleys Ghost]

but why multiply move and strafe per 3?

 

 

First number I hit

 

oddly multiplying by 1 works as well ...

[DarthRaff]

Thankyou very much

[Marleys Ghost]

Thankyou very much

 

 

No Problems .. glad it helped.
