◆ contentScaleRatio

float TiltFive.ScaleSettings.contentScaleRatio = 5f

The scaling ratio relates physical distances to world-space units.

This value defines how distance units in world-space should appear to players in the real world. This is useful for initially defining a game world's sense of scale, as well as for CAD applications. Use this value alongside to choose the desired physical units (e.g. centimeters, inches, etc). Afterwards, use for cinematic or gameplay purposes.

Suppose that we want to display a bedroom scene that is 10 units across in world space. Also suppose that a person standing in this virtual bedroom would measure that distance to be 4 meters. In this case, we want 10 in-game units to represent 4 meters. Dividing 10 by 4 gives us 2.5, so contentScaleRatio should be set to 2.5 for the player to perceive the virtual space at a 1:1 ratio with reality, assuming is set to meters. If the room was now too large for a comfortable experience using the game board, we could change to inches, and the room would appear to be 25 inches across, now entirely visible within the borders of the game board.

The content scale, in terms of meters per world space unit.

This value can be useful for gravity scaling. Simply divide Earth gravity (9.81m/s^2) by the product of this value and the game board scale.

Suppose the content scale is set to 1:10cm. Using Unity's default gravity setting, the player would see an object in freefall appear to accelerate 1/10th as fast as expected, which could feel unnatural if the game is meant to be perceived as taking place on the table in front of them in the player's space. To fix this, a script with a reference to the Tilt Five Manager could call the following on Awake():

Physics.gravity = new Vector3(0f, 9.81f / tiltFiveManager.glassesSettings.physicalMetersPerWorldSpaceUnit, 0f);
