Scripted Sequences Tutorial
Document Summary: A brief guide to using Scripted Sequences.
Document Changelog: Last updated by Chris Linder (DemiurgeStudios?). Original author was Hugh Macdonald (UdnStaff).
Scripted Sequences are used to control pawns in scenes. In your ScriptedSequence actor, under AIScript
is a dynamic array of Actions
Using a Dynamic Array
Initially, your Actions array will be empty. To add a new action, click on Add
. This will create an empty element in the array (Add
will always create elements at the end of the array). If, at any point, you click on Empty
, it will clear the whole array, and you will lose any data that was in it.
Once you have an empty element in the array, you can expand it, and get a drop-down box which lists all the items which can be added into the array. To create a specific item for the array, select the item you wish to use from the drop-down-box, and click on New
. The item that has been created can then be expanded to allow access to its variables.
To clear an element in the array, go to the main holder for that element (with the array index, eg 
), and click on Clear
. This will leave the actual element, but remove all the contents. To remove an element completely, click on Delete
. If you wish to insert a new element before the current one, you can click on Insert
To change the contents of an element, you must clear it first, and then create the new content.
Using the ScriptedSequence
To link a pawn to a ScriptedSequence, you need to set the pawn's AIScriptTag
to the Tag
of the ScriptedSequence. This will cause the sequence to start executing as soon as the pawn is active in the level (usually as soon as the level begins). Because of this, the most useful command to have first in the ScriptedSequence is a WaitForEvent
. Once you have set this, you can then wait to trigger the rest of the sequence.
Any actions that you can use in a ScriptedSequence are described fully in the Actions
