I'm new to Unreal Development.
In a nutshell, how do I create a button, install it in a basic game, and capture the button click event?
We can send messages from flash to UDK with the ActionScript command fscommand( "mycommand" )
For example, we want a button that permit us exit from the game
With ActionScript, we asign the function fscommand("exit") to the click button event
From kismet we can receive the pulsation of the button, for this:
New event -> GFx Ui -> fscommand
Inside the properties, we have two that are necessary, Movie and FSCommand
On Movie we'll put the flash movie that we are using ( button with green arrow ) and in FSCommand we write the command that we are waiting for, in that case Exit
We can connect the exit to that we want to happen when the signal was sended from Flash.
With this example, we are created a "Console Command"
New Action -> Misc -> Console Command
The accepted answer is outdated. FScommands are deprecated and slow.
Try using scaleform CLIK and:
