Player Class

This class is used to create cameras that view the world. Their viewing frustum is defined by a near clipping plane, far clipping plane and the field of view. Note that if you set up a custom model-view or projection matrix and after that call any of these functions:

your custom matrices will be overwritten.

Objects, decals and lights can be selectively displayed in the player viewport. To be displayed, their viewport mask should be matching with the player's viewport mask (one matching bit is enough):

Reflections can also be selectively rendered into the viewport: an object can be rendered without reflection or reflection without an object. For that, the player's reflection mask should match with:

That is enough to render reflection from the object without an object itself. If an object needs to be present as well, all these conditions should simply go together with above mentioned ones.

To render an object without reflection, simply either its material viewport mask or object surface viewport mask should not match the player's reflection mask.

Players cannot have a parent node; they always use the world coordinates for their transformations. The only exception is PlayerDummy.

Members


void flushTransform ()

Forces to immediately set transformations to the player. This function should be called manually after user input has been updated via updateControls().

Controls getControls ()

Returns a Controls object that holds settings of input controls relevant to the player.

Return value

Controls object used to handle input controls.

float getFov ()

Returns the current vertical field of view of the player. (Horizontal FOV cannot be used since it varies depending on the viewport's aspect ratio.) The default value is 60.

Return value

Vertical field of view in degrees.

mat4 getIModelview ()

Returns the inverted modelview matrix of the player.

Return value

Inverse modelview matrix.

mat4 getModelview ()

Returns the modelview matrix of the player.

Return value

Modelview matrix.

mat4 getOffset ()

Returns an additional transformation (an offset matrix) set for the player. This transformation is applied after the model-view transformation. It does not affect it or the position of the player. For example, the offset matrix can be used to set player's head position (in case the player turns his head) or to simulate camera shake from an explosion. The default value is mat4_identity.

Return value

Offset matrix.

mat4 getOldModelview ()

Returns the modelview matrix of the player used in the previous frame.

Return value

Old modelview matrix.

string getPostMaterials ()

Returns names of the current postprocess materials that are applied after all other postprocess (such as HDR, DOF, etc.) are rendered.
They are used after engine.render.getPostMaterials(), if any.

Return value

Name of the current post postprocess materials.

mat4 getProjection ()

Returns the current projection matrix with unit (1.0) aspect ratio.

Return value

Projection matrix.

int getReflectionMask ()

Returns the current bit mask for rendering reflections into the viewport. Reflections are rendered in the viewport if masks of reflective materials match this one.

Return value

Integer, each bit of which is a mask.

int getReverbMask ()

Returns the current bit mask that determines what reverberation zones can be heard. For sound to reverberate, at least one bit of this mask should match with a reverb mask of the sound source and a reverb mask of the reverberation zone. (Masks of a sound source and reverberation zone can match with the player's one in different bits, not necessarily one).

Return value

Integer, each bit of which is a mask for reverberating sound sources and reverberation zones.

mat4 getSProjection ()

Returns the current shader projection matrix. This matrix can be used for oblique projection clipping planes with correct shadow rendering.

Return value

Projection matrix.

int getSourceMask ()

Returns a bit mask that determines what sound channels can be heard. For a sound source to be heard, its mask should match with this one in at least one bit. Plus, the volume of sound channel in which the sound plays (its number also depends on this mask) should not be equal to 0.

Return value

Integer, each bit of which specifies a sound channel.

vec3 getUp ()

Returns the current direction viewed through the player viewport as upward (i.e. controls the tilting of the camera viewport). The default value is vec3(0,0,1).

Return value

Upward direction vector.

vec3 getVelocity ()

Returns a player's velocity. The default is vec3(0,0,0).

Return value

Velocity in units per second.

int getViewportMask ()

Returns the current bit mask for rendering into the viewport. Object surfaces, materials, decals, lights and GUI objects will be rendered into the viewport only if their viewport mask matches the player's one (one matching bit is enough).

Return value

Integer, each bit of which is a mask.

float getZFar ()

Returns the current distance to the far clipping plane of the player's viewing frustum. The default value is 10000 units.

Return value

Distance in units.

float getZNear ()

Returns the current distance to the near clipping plane of the player's viewing frustum. The default value is 0.1 units.

Return value

Distance in units.

int isControlled ()

Returns a value indicating whether player controls are disabled (player does not respond to them) or enabled. The default value is 1.

Return value

Positive number if player controls are disabled; otherwise, 0.

void setControlled (int mode)

Disables or enables player controls. The default value is 1.

Arguments

  • int mode - Positive number to disable player controls (player stops responding to them), 0 to enable.

void setControls (Controls controls)

Sets a Controls object that will hold settings of input controls relevant to the player.

Arguments

  • Controls controls - Controls object used to handle input controls.

void setFov (float fov)

Sets a vertical field of view of the player. (Horizontal FOV cannot be used since it varies depending on the viewport's aspect ratio.) The default value is 60.

Arguments

  • float fov - New vertical field of view in degrees. The provided value will be saturated in the range [0; 180].

void setModelview (mat4 modelview)

Updates a modelview matrix for the player.

Arguments

  • mat4 modelview - New modelview matrix.

void setOffset (mat4 offset)

Sets an additional transformation (an offset matrix) for the player. This transformation is applied after the model-view transformation. It does not affect it or the position of the player. For example, the offset matrix can be used to set player's head position (in case the player turns his head) or to simulate camera shake from an explosion.

Arguments

  • mat4 offset - Offset matrix.

void setOldModelview (mat4 modelview)

Sets the modelview matrix to be used as a previous fame matrix.

Arguments

  • mat4 modelview - Old modelview matrix.

void setPostMaterials (string material)

Sets render postprocess materials that are applied after all other postprocess (such as HDR, DOF, etc.) are rendered.
They are used after engine.render.setPostMaterials(), if any.

Arguments

void setProjection (mat4 projection)

void setReverbMask (int mask)

Updates a bit mask that determines what reverberation zones can be heard. For sound to reverberate, at least one bit of this mask should match with a reverb mask of the sound source and a reverb mask of the reverberation zone.
