GetNameFromId

GetNameFromId allows to get the numerical identifier of an object from its name. This function returns the "_ NULL _" character string if the identifier is not valid.
Syntax
object_name = HYP_Object.GetNameFromId( object_id );
  • object_id - [INTEGER] - object numerical identifier.
  • object_name - [STR127] - object name.

GetIdFromName

GetIdFromName allows to get the name of an object from its numerical identifier. This function returns -1 character string if the name is not valid.
Syntax
object_id = HYP_Object.GetIdFromName( object_name );
  • object_name - [STR127] - object name as specified in the XML script by the "name" attribute.
  • object_id - [INTEGER] - object numerical identifier.

DisplayTripod

DisplayTripod displays or hides the local reference mark (tripod or pivot) of the object.
Syntax
HYP_Object.DisplayTripod( object_name|object_id, state );
  • object_name - [STR127] - object name as specified in the XML script by the "name" attribute.
  • object_id - [INTEGER] - object numerical identifier.
  • state - [INTEGER] - enabled: 1 (TRUE) - disabled: 0 (FALSE).

ResetTripod

ResetTripod allows to re-intitialize the tripod of an object. The tripod of an object is equivalent to its local reference mark, i.e. a structure of data which contains all the information regarding the object transformations (position and orientation). The initialization of the tripod will set the position in <0.0, 0.0, 0.0> and will cancel the orientation.
Syntax
HYP_Object.ResetTripod( object_name|object_id );
  • object_name - [STR127] - object name as specified in the XML script by the "name" attribute.
  • object_id - [INTEGER] - object numerical identifier.

UpdateTripod

UpdateTripod allows to update the tripod of an object. The tripod of an object is equivalent to its local reference mark, i.e. a structure of data which contains all the information regarding the object transformations (position and orientation). The update of a tripod may be necessary to get for example the absolute position of an object. The HYP_Object.SetPosition() function modifies only the relative position of the object. If this object belongs to a complex hierarchy, only the HYP_Object.GetAbsolutePosition() function allows to get its position compared to the world reference mark (absolute reference mark). Normally, the tripod is updated once per frame but if its relative position is changed with a LUA script, and that the absolute position is needed later on, a call to HYP_Object.UpdateTripod() is necessary.
Syntax
HYP_Object.UpdateTripod( object_name|object_id );
  • object_name - [STR127] - object name as specified in the XML script by the "name" attribute.
  • object_id - [INTEGER] - object numerical identifier.

SetMaterial

SetMaterial allows to attach a material to an object. It is recommended first to call the HYP_Object.ClearAllMaterials() function in order to correctly initialize the internal list of the object materials.
Syntax
HYP_Object.SetMaterial( object_name|object_id, material_name|material_id );
  • object_name - [STR127] - object name as specified in the XML script by the "name" attribute.
  • object_id - [INTEGER] - object numerical identifier.
  • material_name - [STR127] - name of the material as specified in the XML script by the "name" attribute.
  • material_id - [INTEGER] - numerical identifier of the material.

ClearAllMaterials

ClearAllMaterials allows to remove all the materials of an object. After this function has been called, it is absolutely necessary to attach at least one material to the object, otherwise it will not be correctly rendered.
Syntax
HYP_Object.ClearAllMaterials( object_name|object_id );
  • object_name - [STR127] - object name as specified in the XML script by the "name" attribute.
  • object_id - [INTEGER] - object numerical identifier.

GetChild

GetChild allows to get a child in the hierarchy of a parent object. If successful, the function returns the identifier of the child; if not, it returns -1.
Syntax
id_child = HYP_Object.GetChild( parent_name| parent_id, child_name );
  • parent_name - [STR127] - name of the parent as specified in the XML script by the "name" attribute.
  • parent_id - [INTEGER] - numerical identifier of the parent.
  • child_name - [STR127] - name of the child you want to know the identifier.
  • id_child - [INTEGER] - numerical identifier of the child.
Remark
This function performs a complete search in the hierarchie of the parent, whatever is the depth of the hierarchy.

GetNumChildren

GetNumChildren allows to get the number of direct children of a parent. The number of direct children of an object is the number of children at the FIRST LEVEL of the hierarchy. If successful, the function returns the identifier of the child; if not, it returns -1.
Syntax
num_children = HYP_Object.GetNumChildren( parent_name| parent_id );
  • parent_name - [STR127] - name of the parent as specified in the XML script by the "name" attribute.
  • parent_id - [INTEGER] - numerical identifier of the parent.
  • num_children - [INTEGER] - number of direct children.

GetChildByIndex

GetChildByIndex allows to get a direct child (first level of hierarchy) of a parent. If successful, the function returns the identifier of the child; if not, it returns -1.
Syntax
id_child = HYP_Object.GetChildByIndex( parent_name| parent_id, index );
  • parent_name - [STR127] - name of the parent object as specified in the XML script by the "name" attribute.
  • parent_id - [INTEGER] - numerical identifier of the parent object.
  • index - [INTEGER] - numerical identifier of the child object.
  • id_child - [INTEGER] - numerical identifier of the child.
Example
function processChildren( parent )
	local num_children = HYP_Object.GetNumChildren( parent );
	local i=0;
	while(i<num_children) do
		id_child = HYP_Object.GetChildByIndex( parent, i );
		DoSomethingWithChild();
		processChildren( id_child );
		i = i + 1;
	end
end

processChildren( "humanModel" );


Clone

Clone allows to clone an object of the 3d scene.
Syntax

new_object_name );
  • master_object_name - [STR127] - name of the object to be cloned as specified in the XML script by the name attribute.
  • master_object_id - [INTEGER] - object numerical identifier to be cloned.
  • new_object_name - [STR127] - name to be given to the new object resulting from the cloning. This parameter is optional.
  • id_clone - [INTEGER] - numerical identifier of the clone.
Example
local i=0;
while(i<10) do
	id_clone = HYP_Object.Clone( "myMasterSphere" );
	HYP_Object.SetPosition( id_clone,  i*20.0, 0.0, 0.0 );
	i = i + 1;
end

  • BOX (primitive)
  • SPHERE (primitive)

  • name - [STR127] - object name as specified in the XML script by the "name" attribute.
  • id - [INTEGER] - object numerical identifier.
  • state - [BOOLEAN] - enables (1) or disables (0) the vbo use.

HYP_Object.SetRenderState( "mySphere2", TRUE );

GetRenderState

GetRenderState allows to get the rendering state of an object.
Syntax
state = HYP_Object.GetRenderState( name | id );
  • name - [STR127] - string character representing the name of the object as specified in the XML script by the "name" attribute.
  • id - [INTEGER] - object numerical identifier.
  • state - [BOOLEAN] - TRUE (1): enabled - FALSE (0): disabled.
Example
TRUE = 1;
FALSE = 0;
if( HYP_Object.GetRenderState("mySphere1")==FALSE ) then
	HYP_Object.SetRenderState("mySphere1", TRUE);
end	

SetActiveState

SetActiveState allows to control the active state of an object. In the oZone3D engine, an object has 3 fundamental states: the ACTIVE, UPDATE and RENDER states. A very simplified version of the states management algorithm is as follows:
function MainEgineLoop()
	do_some_stuffs();
	
	if( object.active_state==TRUE ) then
		
		if( object.update_state==TRUE ) then
			object.update();
		end
		
		if( object.render_state==TRUE ) then
			object.render();
		end
	end

	do_some_stuffs();
end	
According to this code, you see that if an object has its RENDER state set to false, it will not be rendered but it will always be updated. On the other hand, if its ACTIVE state is set to false, it will neither be rendered nor updated.
Syntax
HYP_Object.SetActiveState( name | id, state );

  • y - [REAL] - Y coordinate.
  • z - [REAL] - Z coordinate.

GetAbsoluteTransformMatrix

GetAbsoluteTransformMatrix gets the absolute transformation matrix of the object's pivot (or local reference mark). The absolute transformation matrix expresses the transformation of the object's pivot compared to the reference mark of the world (universal reference mark). This absolute transformation matrix is a 4x4 square matrix organized as follows:
|x'|   | m0   m4    m8    m12 |   |x|
|y'| = | m1   m5    m9    m13 | * |y|
|z'|   | m2   m6    m10   m14 |   |z|
|1 |   | m3   m7    m11   m15 |   |1|

		--    --    --    --
		 X     Y     Z    Position
		axis  axis  axis
As an example, the absolute position is given by the {m12, m13, m14 } triplet.

The oZone3D uses columns vectors and the matrices multiplication from right to left. It is the standard OpenGL convention.
