RTPC

A RTPC allows you to synchronize a value between your game and Amplitude. With Amplitude, you can update several values automatically through RTPC, such as sound object gain and priority, as well as effect parameters.

An RTPC object is described by the following properties:

id¶

uint64 required

A unique value across RTPC assets that represents the ID of this object. It may be reused later to get the instance of this RTPC from the engine at runtime.

name¶

string required

A unique value across RTPC assets that represents the name of this object. It may be reused later to get the instance of this RTPC from the engine at runtime.

min_value¶

double required

The minimum value the RTPC is allowed to have.

max_value¶

double required

The maximum value the RTPC is allowed to have.

default_value¶

double default: 0.0

The default value assigned to the RTPC at initialization. If this value is outer of the range [min_value, max_value], it will be clamped in that range.

fade_settings¶

RtpcFadingSettings required

This property allows you to customize the fade transition for when the RTPC value increase or decrease. It takes as value an object with the following properties:

enabled¶

bool default: false

Defines whether the RTPC value should fade on change. If false the new value will be set without transitions.

fade_attack¶

FadeTransitionSettings

Settings for the fade transition to apply when RTPC value is increased. The value should match the schema of a FadeTransitionSettings object.

fade_release¶

FadeTransitionSettings

Settings for the fade transition to apply when RTPC value is decreased. The value should match the schema of a FadeTransitionSettings object.
