collisions

[cassius]

My character walks straight thru this door. Am I missing something?

 

 

 

void setup_door()

{

door.pivot = Pivot::Create();

door.pivot->SetCollisionType(Collision::Prop);

 

 

door.pivot->SetPosition(-239.9,9.46,316.03);

door.model->SetPosition(door.pivot->GetPosition());

door.pivot->SetMass(0.0);

}

EDIT: The door is in closed position

If the door is a model, does the door have a phy file, or does it have a shape? That's the first thing I would think of. Another question is, is the door a child of another object (do you have to click + to get to it)?

[cassius]

The door is placed in position with the code, not in the editor.

What is door->model? A 3D model I assume? Does it have a physics shape attached to it? With external models you have to assign a physics shape to it yourself (or csg). Probably best to make a prefab of the door where you give it a shape or attach csg with a script attached to it so the csg won't get collapsed.

[cassius]

Can I assign a shape in code?

[cassius]

Does this look ok.

 

 

 

door.model->SetPosition(-239.9, 9.46, 316.03);

Shape* doorshape = Shape::Box();

door.model->SetShape(doorshape);

door.model->SetCollisionType(Collision::Prop);

door.model->SetMass(0.0);

doorshape->Release();

You now need to scale the box, or create the box to the same dimensions of your door otherwise, they might slide past it.

[cassius]

Yeah I was considering that. It works ok as it is, but I may try placing it in the editor and use its classname as reference.

Thanks for help.

@Cassius :

 

door.pivot->SetCollisionType(Collision::Prop);

A pivot is an empty object, it don't need collisions.

 

Why not creating all in the editor instead coding ? I mean place a door model and physics, place the pivot as child object of door, than use simple code , for example : door.FindChild("pivotDoor")

The advantage is that visually you can see and adjust your pivot of your door, and save door with script and child pivot as a re usable prefab.

[Einlander]

Yougroove he is using c++ so I would assume that he has a door class that has a pivot member and a model member. Even in lua you can create a pseudo class and create a door without the joint feature. It's a method of containing everything that is related to the door in one compact self contained package.

[YouGroove]

I meaned , it could have pivot child and door in the editor and save them as prefab, than re use them in the editor by duplicating them.

-Design, physics, pivot placement in the editor and save as prefab

-Find prefab instance in C++ and use FindChild (pivot child in the prefab object) in C++

Just another way of working.

The idea in my game is this: Main character walks into room. Enemy closes door from outside locking main character in rom.

The door is open and then closes.After that it is never opened again.A sliding door might be easier but I will try normal door first using code.

 

II don;t think I need pivot.
