ObjectMeshSkinned Class

List of Functions:

This class is used to create or modify skinned meshes.

Skinned meshes are used for bone-based animation.

Creating and Playing Animation

To add the animation to the ObjectMeshSkinned and play it, do the following:

Set the number of animation layers with the setNumLayers() method. There is only one layer by default.
Enable the layer and set the animation weight for blending by calling the setLayer() function.
Add the animation .anim file by using addAnimation() or setAnimation() functions.
Play the added animation by calling the setFrame() function for each animation layer.

Blending is performed between all layers. The contribution of each layer depends on its weight. Also, you can optionally define single bone transformations by hand, if needed, using either setBoneTransform() or setBoneChildsTransform().

Usage Example

The following example shows how to blend 2 different animations assigned to a mesh. In this example we use the mesh and animations from UNIGINE samples located in <UnigineSDK>/data/samples/animation/meshes and <UnigineSDK>/data/samples/animation/animations folders, respectively. Animations are added by using the addAnimation() function.

Source code (UnigineScript)

// define the new ObjectMeshSkinned class instance
ObjectMeshSkinned skinned_mesh;

int init() {
	/* ... */
	// create the new ObjectMeshSkinned mesh based on an existing mesh
	skinned_mesh = new ObjectMeshSkinned("samples/animation/meshes/agent.mesh");

	// add the material and the property to the mesh
	skinned_mesh.setMaterial("mesh_base","*");
	skinned_mesh.setProperty("surface_base","*");
	// add the mesh to the editor
	engine.editor.addNode(node_remove(skinned_mesh));
	
	// set the number of animation layers
	skinned_mesh.setNumLayers(2);

	// load animations from the files
	int animation_1 = skinned_mesh.addAnimation("samples/animation/animations/agent_run.anim");
	int animation_2 = skinned_mesh.addAnimation("samples/animation/animations/agent_punch.anim");

	// enable each layer and set an animation weight
	skinned_mesh.setLayer(0,1,0.7);
	skinned_mesh.setLayer(1,1,0.3);

	// set animations to layers
	skinned_mesh.setAnimation(0, animation_1);
	skinned_mesh.setAnimation(1, animation_2);

	/* ... */
}

int update() {
	/* ... */
	// get the current time spent in the game
	float time = engine.game.getTime();

	// start each animation playing
	skinned_mesh.setFrame(0,time * 25.0f);
	skinned_mesh.setFrame(1,time * 25.0f);
	/* ... */
}

Updating Bone Transformations

Some of the methods require to update the animation data before the renderer makes its update and actually draws the skinned mesh. Such update allows to get the correct result of blending between the frames and layers.

The execution sequence of updating bone transformations is the following:

Call the method, which sets the update flag. This flag shows that the instance should be updated.
Update the bone transformations by calling proper functions. These functions check the flag and if the flag is set, they calculate the transformations and set the flag to the default value.
During the rendering, the engine performs animations and transformations which were calculated on the previous step or recalculates them, if the update flag has been set. If calculations have been performed, the flag is set to the default value.

If you try to update bone transformations before you set the flag to update, functions will not calculate new transformations and the engine doesn't perform them.

When you change the transformation of the bone, you should notify all skinned meshes which use these bone about these transformations to update the mesh. When you change transformations of a bone, skinned mesh instances get the flag to update. When you use the setFrame() function, you set necessary transformations for the specified skinned mesh.

Instancing

Surfaces of identical skinned meshes which have the same materials assigned to them and the same number of bones attached to their vertices are automatically instanced and drawn in one draw call. The instancing flag is enabled by default (see corresponding console commands).

The data buffers for instanced objects that store bones transformations are limited in size; therefore, if skinned meshes have many bones, only a few meshes can populate the instance data buffer to be drawn in one draw call.

NoticeThe higher the number of bones and the more bones are attached to one surface, the less robust instancing will be.

int target - Number of a target.
float weight - Target weight.
int surface - Surface number.

void setTarget (int target, int enable, int index, float weight, int surface)

Sets all parameters to a given morph target.

Arguments

int target - Number of a target.
int enable - Enabling flag. 1 to enable the morph target; 0 to disable it.
int index - Target index.
float weight - Target weight.
int surface - Surface number.

void setTexCoord0 (int num, vec2 texcoord, int surface)

Sets new coordinates for the first UV map of the mesh surface.

Arguments

int num - The number of the vertex in the vertex buffer.
vec2 texcoord - Coordinates of the first UV map to be set.
int surface - The number of the mesh surface.

void setTexCoord1 (int num, vec2 texcoord, int surface)

Sets new coordinates for the second UV map of the given mesh surface.

Arguments

int num - The number of the vertex in the vertex buffer.
vec2 texcoord - Coordinates of the second UV map to be set.
int surface - The number of the mesh surface.

void setTime (float time)

Sets the animation time, in animation frames. The time count starts from the zero frame. If the time is set to be between frames, animation is blended. If the time is set outside the animation frame range, the animation is looped.

Notice

The setTime() function corresponds to the Play and Stop options in the editor. In all other cases use setFrame() to set the animation.

Arguments

float time - Animation time.

void setVertex (int num, vec3 vertex, int surface, int target = 0)

Sets new coordinates for the given vertex.

Arguments

int num - The number of the vertex in the vertex buffer.
vec3 vertex - Coordinates of the vertex to be set.
int surface - The number of the mesh surface.
int target - The number of the surface morph target.

void setWorldBoneChildrenTransform (int bone, mat4 transform)

Sets transformation for the bone and all of its children in the world coordinate space (considering node transformations). Take notice that bones can be scaled only uniformly.

Arguments

int bone - Bone number.
mat4 transform - Transformation matrix.

void setWorldBoneChildsTransform (int bone, mat4 transform)

Sets transformation for the bone and all of its children in the world coordinate space (considering node transformations). Take notice that bones can be scaled only uniformly.

Warning

The function is deprecated. It is provided to keep your code working until the next release. Please, replace it with setWorldBoneChildrenTransform().

Arguments

int bone - Bone number.
mat4 transform - Transformation matrix.

void setWorldBoneTransform (int bone, mat4 transform)

Applies transformation to a bone in the world coordinate space. Take notice that a bone can be scaled only uniformly.

Arguments

int bone - Bone number.
mat4 transform - Transformation matrix in the world space.

void stop ()

Stops animation playback. This function saves the playback position so that playing of the animation can be resumed from the same point.

void updateSurfaceBounds (int surface = -1)

Updates mesh bounds.

Arguments

int surface - The number of the mesh surface.
Notice
Specify -1 to select all surfaces.
