Hi Li :) #26

Open LucaEstiva opened 11 years ago

LucaEstiva commented 11 years ago

The constraint ( hinge ) can be succesfully moved ( initially the constrained object moves a bit away from the constraint but... ) . So the constraint can now be placed at the right pinball palette position ! ( I have spent some times for work with the program interface, materials, material methods, Lua scripts, lights, camera, ecc but the phisycs remain a priority in Game Maker ! ) so, for now, thanks Li !

I think i need a panel or a window to edit physics material properties like restitution for example ( simulate a soft ball ) the mass which is set to 0 make the object static and not dynamic.

Thanks Li ! Hey i can also add physics to point lights :) I'm excited !!! physicslight

muzerly commented 11 years ago

Hi, I have added setAxis function in hinge joint, update it in dev branch

LucaEstiva commented 11 years ago

Hi Li, really thanks !

What I need to do, is a software that is like MAX or MAYA or BLENDER or Unity. And for now Game Maker promising … ;)

So after i have composed all my scenes ( video, HUD or menu, 3DScene ( means all, animation, physics, particles systems, effects ( light, post process, ecc ), ecc ecc ) I need I way to thake all this

and make it playable. ( switch scenes can be caused by Time, Events, User action, ecc )

Games Maker use a pieces of software ( engine ) that can be used as “interpreter” so I think I need a “player” like Unity….

For example I can add a camera to one scene object and switch the camera if Games Maker enter “play”, or i must see, “simulation” mode… ( These are different… )

Now I need to manage all the “object” that Away 3D expose, this means Games Maker must be able to Add, Clone, Array, Delete, Modify all the properties, Moves, Align, Edit mesh by using “modifiers” simply access the vertex data… ecc ecc ecc

Add modeling, mesh animations ( bones graphically this is not to hard J I think a container “local transform” and Meshes or Line segments ;) ), texture painting features

I need to see if access and/or manage mesh faces can be made… For example by using segments to highlights these faces…

Add vertex to these mesh and so on..

And others type of modifiers like cut plane, melt, explode, shell ecc. Away already have some of this kind of “modifiers”…

This means that the object management must go in deep…

Obviously I can import objects from max for example… and for now this is the only way ( for now ) to have animated mesh, for example…

Manage all this is not simple, and I need to start with the basic and go in deep…

And because I have more than one method to implement at all, Games Maker are stable and instable ….

As you certainly know MAX use reactor first, MassFX now (NVidia PhysX) or Bullets in Blender J. Now, I need to manage all Physics properties by using the graphic interface so in this way I can make Games, Simulation, Simple scenes ecc ecc simply by using Games Maker, Away3D, and Away Physics...

I’m working on !!! J Thanks !

LucaEstiva commented 11 years ago

Now I'm in trouble... I know that i C(C++ a pointer is a memory address. The pointer math is clear, If i have a pointer to a byte ( char for example ) the next momery address ( suppose the first address is 1, and suppose the mem align is byte... not padded ) the Pointer++ incremet the pointer ( the pointed memory address ) , so the new memory address is 2 :) To thake the value store at this address i can use th & operator... I can use pointer to "reference" a struct, a class ( a struct basicly ) or a functions and i can access it's members by using the -> operator, Not the . operator this is another case...

http://www.geeksforgeeks.org/structure-member-alignment-padding-and-data-packing/

Now, Getters and Setters are available in Visual basic for example. This is because, the Hinge constraint can be used to link two objects ;)

hingeconstraint1 hingeconstraint2 hingeconstraint3

The hinge constraint need to know the constraint parameters for two reference point...

public function setAxis(axis:Vector3D):void { setHingeConstraintAxisInC(pointer, axis.x, axis.y, axis.z); }

What is the reference point here A or B :) ? Can i specify the axis for the reference point A or B ?

I can add setters ( AWPHingeConstraint ): public function set axisInA( axisInA:Vector3D ):void { // m_rbAFrame.basis.column3 = axisInA; } public function set axisInB( axisInB:Vector3D ):void { // m_rbBFrame.basis.column3 = axisInB; } and ( AWPMatrix3x3 ):

    public function set column3( column3:Vector3D ):void {
        _row1.z = column3.x;
        _row2.z = column3.y;
        _row3.z = column3.z;
    }

but i have only z here... what this means... ?

Help me Li ... :)

This are the position of the constraint relative to the object ( object space ):

New constraint position: Vector3D(-7.000000029802322, 0, 0) New constraint position: Vector3D(-9.000000357627869, 0, 0) New constraint position: Vector3D(-15.999999642372131, 0, 0) New constraint position: Vector3D(-20.999999344348907, 0, 0) New constraint position: Vector3D(-27.99999713897705, 0, 0) New constraint position: Vector3D(-31.999996304512024, 0, 0) New constraint position: Vector3D(-32.99999535083771, 0, 0) New constraint position: Vector3D(-36.99999749660492, 0, 0) New constraint position: Vector3D(-48.99999499320984, 0, 0) New constraint position: Vector3D(-50.999999046325684, 0, 0) New constraint position: Vector3D(-60.999995470047, 0, 0) New constraint position: Vector3D(-68.99999976158142, 0, 0) New constraint position: Vector3D(-70.99999785423279, 0, 0) New constraint position: Vector3D(-82.99999833106995, 0, 0) New constraint position: Vector3D(-85.00000238418579, 0, 0) New constraint position: Vector3D(-93.00000071525574, 0, 0) New constraint position: Vector3D(-107.00000524520874, 0, 0) New constraint position: Vector3D(-109.00000333786011, 0, 0)

Another question... :) The others constraint can be managed by Games Maker ... ??? I don't know ... :)

Hey Li where are you from... Can i take a look to your country in some way ? I'm here: https://www.facebook.com/luca.filippini.902

LucaEstiva commented 11 years ago

The last thing for today. Sorry Li but i'm really interested to make Games Maker works :). I don't know if you use blender or not, and/or if you have a GREAT DOCUMENTATION, about bullets but i have this:

http://79.0.174.91:8086/Bounce,%20Tumble,%20and%20Splash!%20Simulating%20the%20Physical%20World%20with%20Blender%203D.pdf

You can take a look in to the main folder. I have more and more but, as you know...

muzerly commented 11 years ago

hinge constraint is a fixed axis constraint, in bullet engine there is no a function to set axis in pivotA and pivotB separately. In other constraints you can set pivot and axis separately.

I'm from China. I can't visit the facebook link bacause the great firewall.

muzerly commented 11 years ago

yea, I use blender and unity3d. thanks for the link.

LucaEstiva commented 11 years ago

This means i must set the axis when i create the constraint and after i can’t change that axis. I’m confused:

http://bulletphysics.org/mediawiki-1.5.8/index.php/Constraints

Normally two axis in hinge-connected objects should align and point to the same direction, such as a door. But you can set two axis as different vectors.

btHingeConstraint( btRigidBody& rbA,

              btRigidBody& rbB,

              const btTransform& rbAFrame,

              const btTransform& rbBFrame,

              bool useReferenceFrameA = false )

Yes I can impose that…

Anyway for now i “can try to implements” ;) the others constraint…

Thanks to you Li …

( about the firewall Proxy server ? ;) )

no, you can use setAxis function change the axis realtime. but the axisInA and axisInB should be always equality.

LucaEstiva commented 11 years ago

Sry Li, i have two objects, and two matrix…

Or may be I have a “container” and in this case I can multiply the matrix of the object1 by the container matrix and the matrix of the object2 by the container matrix, in that way I have the final transformation that refer to the container transformation.

Like normal World, View, Projection or:

finalTransform.identity();

finalTransform.append(world);

finalTransform.append(camera);

finalTransform.append(projection);

It’s right for you ?

Not now but i want try to use PhysX:

( I must see the hardware/software compatibility list but i if remember right … there are no problems… )

Firefox and

I think is the function declaration proto that confuse me… , but anyway as usual thank for your help Li

And… i have this comment on my Hinge constraint creation function … J

         * Hinge constraint, or revolute joint, restricts two additional angular degrees of freedom, so the

         * body can only rotate around one axis, the hinge axis.

Sry Li :P ( I’m lost )
