Controller

About

#

Tiled level controller is a new feature in V4.0 which grants you the ability to fully control each placement in a tiled level. It’s where you can add your blueprint code. You can assign a controller class for each level, and then run the logic. Here is a simple tutorial to create some interesting effects.

General Idea

#

The controller provides these types of functions:

1. get, find, and filter placements in guid
2. get placement info from guid
3. get level info
4. hide / unhide placement
5. Transform placement
6. Lerp transform of placement through time

Check out controller_api for all the functions.

You can wisely use them to create any stunning visual presentation for you level.

Setup

#

1. Create an actor inherit from tiled level controller

1. Set the controller class in either way
   • on level asset

• on the level on map

Example effects

#

Prepare float curves

#

Lerp transform through time would require some curve assets.

You can create them this way:

Add key and edit. The length should be the duration of your animation.

Assemble effect

#

Open the controller actor and add these logic

1. set the transform of each placement to a random position

• Create variable RandomInitTransforms (array of transform)

• run update transform to let each placement move back to it’s origin transform

• Create variable Id (integer), to use index way to loop. (in order to add delay)

• Use the curves you previous created.

• Trigger it on begin play!

Final assemble me

Growth effect

#

1. Create BatchGrowth event

   

   • Create variable Defaults and Smalls (array of transform)
   • Use the curves you previous created.
2. Create RunBatchGrowth event

   

   

   • Create variable Central, Rest (array of guid), and N (integer)
   • Use Search Placement by Tile Position to separate placements in batches from center to outer
   • Run BatchGrowth with some delay
3. Trigger it on begin play!
