Select Value Nodes
Select value nodes are used to select a particular value based on an index. If the index value is 0, the first (top) value will be sent to the value output, if it's 1, the second will be sent, etc..
You can choose the type of value from the value type dropdown at the top of the node.
The index value can be entered, or it can come from another node's output which will be determined during dialogue playback.
Each value provides a field where you can enter the value manually, or the value can come from another node's output.
You can have an unlimited number of values in a select value node.
To add a new value, just click on the 
button.
To remove a value, click on the 
button next to the value you want to remove.
Each select value node contains a dialogue flow input, a dialogue flow output, an integer index value input, a value input for each value (based on the selected type), and a value output (based on the selected type).
