Player Persecutor

A Player Persecutor is a flying camera without a physical body that follows the target node at the specified distance. The exact point of the target it follows is called an anchor. The persecutor can either turn around its target, or its viewing direction can be fixed. This camera is approximated with a sphere, which allows it to collide with objects (but it cannot, for example, push them or interact with them).

Notice

As any transformation of a player forces it to recalculate its inner state (position, direction, angles, and so on), the up direction of the player's viewport may become "negative forward". And then transformation will be recalculated by using this direction, causing flip of the player's basis. To avoid such flipping, the theta and phi angles should be recalculated by using the current viewing orientation of the player.

Creating a Persecutor#

To create a Player Persecutor, do the following:

On the Menu bar, choose Create -> Camera -> Persecutor.
Place the camera somewhere in the world and specify the required parameters via the Parameters window.

A dummy node named Persecutor_Target that represents an anchor is created along with the Player Persecutor. To make any object an anchor of the Player Persecutor, make that object a child of the Persecutor_Target dummy node.

Editing a Player Persecutor#

In the Player Persecutor section of the Node tab, you can adjust the bit masks, viewing frustum parameters, and post-process materials, as well as the specific parameters of the camera described below.

Player Persecutor parameters

Control Parameters#

A set of parameters controlling persecutor movements:

Fixed Angles	Toggles on and off the persecutor's ability to freely rotate around its target. If disabled, the Player Persecutor is oriented strictly in one direction. If enabled, only the phi angle is fixed, the theta can change.
Controlled	Toggles controls of the Player Persecutor on and off (the player's response to them).
Collision	Toggles collisions for the persecutor on and off.
Collision mask	A bit mask defining nodes the Player Persecutor is able to collide with.

Anchor Coordinates#

Coordinates of the anchor point:

Target node	The anchor node to which the Player Persecutor is bound. By default, the Persecutor_Target dummy node created together with the Player Persecutor is set as a target node. Any node existing in the World hierarchy can be selected as a target node via the drop-down window.
Anchor point	Coordinates of an anchor point along the X, Y, and Z axes (in local coordinates of the target node), to which the persecutor is bound.

Distance Parameters#

A set of distance parameters:

Min Distance	The minimum possible distance between the persecutor and the target.
Max Distance	The maximum possible distance between the persecutor and the target.
Min Theta	The minimum theta angle (zenith angle, also known as pitch angle) that determines how far upward the player can look.
Max Theta	The maximum theta angle (zenith angle, also known as pitch angle) that determines how far downward the player can look.
