[Solved] Dof with Callback
I'm back with new thread 
I try to put in my project dof effect using PhysHitCallback. But I had same errors. Yesterday I thought about it and actually code is look like this:
Code:
Bool Dof::hit(PhysHit &phys_hit)
{
if(Chr *chr=CAST(Chr,phys_hit.obj))
{
if(Player *plr=CAST(Player,phys_hit.obj))
{
}else
{
ray_hit =true;
ray_hit_pos=phys_hit.plane.p;
new_z =phys_hit.dist; //set new z focus to ray hit distance
}
}else if(!ray_hit) // jesli jeszcze nie trafil w ogole
{
ray_hit =true;
ray_hit_pos=phys_hit.plane.p;
new_z =phys_hit.dist; //set new z focus to ray hit distance
}
return true; // zawsze kontynuuj
}
void ADoF()
{
Vec pos,dir;
Dof adof;
if(crossDraw)
{
if(Ms.hidden())
{
pos=Cam.matrix.pos;
dir=Cam.matrix.z;
}else
{
ScreenToPosDir(Ms.pos,pos,dir);
}
Physics.ray(pos,dir*ViewportActive.range,adof); // cast a ray from camera and check if it hits something
// set new depth of field z focus
D.dofPzr(1,LerpTime(D.dofZ(),adof.new_z,0.001),18);
}else D.dofPzr(0,0,0);
}
Everything will be ok but I don't know where I can put this line
Code:
new_z =ViewportActive.range;
which change z parametr when Physics.ray hits nothing. Can anybody help me?

RE: Dof with Callback
please try something like this
Code:
struct Dof : *Callback*
{
Bool ray_hit;
Vec ray_hit_pos;
Flt new_z;
Dof(){ray_hit=false; new_z=ViewportActive.range;} // here you can optionally set 'ray_hit_pos' too if you use it
Bool hit(PhysHit &phys_hit)
{
if(Player *plr=CAST(Player,phys_hit.obj))
{
}else
{
if(!ray_hit || phys_hit.dist<new_z) // if haven't hit yet, or new hit is closer than the previous one
{
ray_hit =true;
ray_hit_pos=phys_hit.plane.p;
new_z =phys_hit.dist; //set new z focus to ray hit distance
}
}
return true; // always continue
}

RE: Dof with Callback
I use this code but i have sth like this http://img93.imageshack.us/img93/8969/scrsh2k.jpg
All the time. But when I delete this || phys_hit.dist<new_z everything is ok except objects Chr, because ray don't find them or sth like this. So in older code I have
Code:
if(Chr *chr=CAST(Chr,phys_hit.obj))
{
if(Player *plr=CAST(Player,phys_hit.obj))
{
}else
....
I put new_z=ViewportActive.range; in constructor as you wrote but nothing happens.

RE: Dof with Callback
please try using debugging in your callback function, and after it
also please check Physics.draw if you see that all actors are setup correctly

RE: Dof with Callback
I debugg this a lot of times and always I see that in Bool Dof::hit(PhysHit &phys_hit) new_z is changing correct but when application go forward and is after ray testing new_z is automatically set to 0. I use only one new_z variable.

RE: Dof with Callback
then check what actor makes the collision which results in "0" value

RE: Dof with Callback
Now I saw sth strange. On the first time phys_dist value is for example 11 but on the second time it's equal 0 and again 11 and 0 and it's all the time.

RE: Dof with Callback
please check to what object points the phys_hit.obj when phys_hit.dist is equal to 0

RE: Dof with Callback
At least! I fixed this I made stupid mistake. I write it here because maybe it will be useful for someone:
Code:
void Player::create(Game::ObjParams &obj)
{
ctrl.createCapsule(0.5,2.1,pos());
__super::create(obj);
}
Before I had:
Code:
void Player::create(Game::ObjParams &obj)
{
__super::create(obj);
ctrl.createCapsule(0.5,2.1,pos());
}
EDIT: I tried this in another model abd now this capsule isn't working. How can I fix this  ??

RE: Dof with Callback
if you want a custom sized capsule then you should create a physical body (check documentation\creating games\importing character meshes)
