Interactive Cutscene Documentation

Keys: I'll explain this at the end.

Type: There are 3 types of key prompt types.

1. Press: Succeeds when the player presses the shown key/button on the screen before the timeout.
2. Hold: Succeeds when the player holds down the shown key/button on the screen before the timeout.
3. Spam: Succeeds when the player spams the shown key/button on the screen enough times before the timeout.

Hold Time: Only relevant when the Type's set to Hold.  Obviously it determines how long should the player hold down the popped key in order to end the key prompt.

Spam Times: Only relevant when the Type's set to Spam.  How many times should the player hit the button to succeed?

Slomo: Slow motion on key show up, range[-1,1]  Controls the game's time dialation; 0 pauses the game and negative values won't touch the time dialation.

Position: [-1,1] Determins the location of the key prompt. X is for the horizental axis, 1: Right | 0: Center | -1:Left and Y is for the vertical axis, 1: Top | 0: Center |  -1: Bottom. You can pretty much pop the key up anywhere you wish on the screen.

Timeout: You can set a limit for the player to succeed if they couldn't it will timeout and they will fail and the key will hide.

On Key Down: Executes every time the player presses the prompted key.

On Key Up: Executes every time the player releases the prompted key.

On Success: Fires when the player succeeds. Pressed, Holds or Spam the key correctly.

On Timeout: Fires when the player misses the key prompt.

Get Keys From Input Action

You can also use this function to get all of the keys mapped to a certain input action in a mapping context with respect to the selected platform.

I'm not gonna go through the parameters that were explained previously, if you haven't read 'em yet just scroll up and read.

Sequencer: The sequencer you wish to pop a key prompt in.

Idle Behavior: Determines what happens when player's doing nothing.

Nothing: Takes no action
Pause: Pauses the sequencer where the playback is.
Rewind: Plays the sequencer backwards till the initial point.

Play Amount: Only relevant if the type's set to Hold or Spam. It determines how much should the the sequencer play forward at the end of the key prompt. for example for Hold, when the player finishes up holding the key the playback position will be at (Initial Position + Play Amount).

Rewind Start Delay (In Seconds): Only relevant if Type's set to Spam and Idle Behavior is set to Rewind. It determines how long after the last key release should it start rewinding 

Rewind Decrement Rate (In Seconds): This only works if the Type's set to Spam and Rewind is selected. It will play the sequencer backwards this much in every second.
For instance if you set it to 2 it means every second the playback will play backwards for 2 seconds!
