Important:

BP_PrizeAnim must be present somewhere in the Level, 

as it is the actor which generates the preview of the Toy you've just got.

 (Can be hidden behind a wall or under the floor for example). 

Applications

-Make your games last longer adding Arcade Claw Machines and achievements about collecting the items got from them.

-Retain players during more time rewarding them with Tokens to play the Arcade Machine to get special Gear and Bonuses. Not just figures and collectible items, unlockables as clothes or powerups can be obtained from the Arcade Machine.

-The Arcade Claw Machine comes as a Ready to Play project. You can just add more items and easily make a game about collecting them. Great for mobile games where the player has to come back later or watch a Video in order to keep playing. You could even make players exchange repeated items online (that feature is not included in the project).

-As a decoration. Give a nice touch to your environments for games or animations adding the arcade machines even if they aren’t working.

Machines Blueprint

The Blueprint is ordered in named sections to easily find the one you want to adjust.

How to Change Claw Speed

The blueprint called BP_ArcadeClawMachine contains the code to change the Claw Speed.

Inside the blueprint there's comment boxes that indicate what each section does.

Find the "Crane Movement Forward and Backward" and "Crane Movement to the sides" comment boxes. 

And inside them you will find "Add" nodes which add +0.1 or -0.1, change the 1 for a bigger number to increase the speed.

Note: The speed also depends on the performance of your computer, specially if you are using the latest UE versions.

How to add your own Prizes to the game:

Add the Level Editor you can just drag any Skeletal Mesh Inside the Machine with the proper Physics and Collision configuration and it should be ready to be catched by the Crane.

Here you can see the default configuration used in order to make the included toys work:

If you want also to make the object collectible and recognized as an Item from the list you should add it to the variables “PrizeList” (Skeletal Mesh), “ToyIconList” (Image file) and “ToyNameList” (name you want to give to the Prize) inside BP_ArcadeToyGameInstance. Make sure the naming is similar to the ones included to avoid errors.
