SET CAMERA TO FOLLOW
This command automatically controls the camera to provide a tracking system.
Syntax
SET CAMERA TO FOLLOW X, Y, Z, Angle, Distance, Height, Smooth, Collision
SET CAMERA TO FOLLOW Camera Number, X, Y, Z, Angle, Distance, Height, Smooth, Collision
Parameters
Camera Number
Integer
The camera number
X
Float
The x value of the target object
Y
Float
The y value of the target object
Z
Float
The z value of the target object
Angle
Float
The angle value of the target object
Distance
Float
The distance value specifies the required distance between the coordinate and the camera
Height
Float
The height value specifies the required height of the camera in 3D space
Smooth
Float
The smooth value specifies the level of smoothing required for the camera, where a value of 1.0 is no smoothing and a value of 100.0 is lots of smoothin
Collision
Integer
The collision value is a special flag that allows the camera to detect whether it is hitting any of the static collision boxes and if set to one will automatically adjust so as not to enter these collidable areas
Returns
This command does not return a value.
Description
By providing the 3D world coordinate of the entity you wish to track, and some camera data, your camera will automatically update its current position each time this command is called. The X, Y, Z and Angle values provide the coordinate to track. The Distance value specifies the required distance between the coordinate and the camera. The Height value specifies the required height of the camera in 3D space. The Smooth value specifies the level of smoothing required for the camera, where a value of 1.0 is no smoothing and a value of 100.0 is lots of smoothing. The Collision value is a special flag that allows the camera to detect whether it is hitting any of the static collision boxes and if set to one will automatically adjust so as not to enter these collidable areas
The fastest code is the code never written.
