Does that mean Blueprints are a replacement for UnrealScript? Yes and no. At the same time, while Blueprints are not meant as a replacement for UnrealScript, they do serve many of the same purposes that UnrealScript handled, such as:. The expectation is that gameplay programmers will set up base classes which expose a useful set of functions and properties that Blueprints made from those base classes can use and extend upon. Blueprints can be one of several types that each have their own specific use from creating new types to scripting level events to defining interfaces or macros to be used by other Blueprints. A Blueprint Class , often shortened as Blueprint , is an asset that allows content creators to easily add functionality on top of existing gameplay classes.

Blueprints work by using graphs of Nodes for various purposes - object construction, individual functions, and general gameplay events - that are specific to each instance of the Blueprint in order to implement behavior and other functionality.

You have your value, check if the value is in range, and use branches to change the color accordingly. I made a sphere that will change color based on a value that increases every tick, this should work for you:. So it returns true on the first check and is done.
