Exploding Barrel

This page shows you how to use a Damage Volume and Target to create damaging traps.. You can apply the same principles with different types of triggers, interactions and switches based on the game you want to create.

Required Nodes & Objects:

1x Sphere Damage Volume

1x On/Off Node

1x Remove Node

1x Set Visibility Node

1x Target Cylinder

1x Explosion

1x Barrel 1A

Place Barrel

There are a few barrels in Arcadia, pick the one that suits you best. I used Barrel 1A

Place Cylinder Target

Cylinder target acts as a volume that the player can attack. Place it over your barrel, so you can't see it anymore.

Place Remove node

Place a Remove node near your barrel & remove node.

Link Remove Node to your Barrel

Event: Act On → Barrel (You may need to more your Target Cylinder to select the barrel)

Event: Act On → Target Cylinder

Link Target Cylinder to Remove Node

Event: On Destroyed → Function: Activate

If you play test at this point, you will be able to shoot your cylinder, and it will disappear when it is destroyed

Kill nearby actors

An exploding barrel that does no damage isn't very useful.

Place Sphere Damage Volume on top of your barrel.

Set it's radius to 10

Enable Kill Instantly

Activate damage volume

Place an On/Off node

Connect Event: On Destroyed → Function: Activate from Target Cylinder to On/Off node

Connect Event: Turn On/Off → Function: Turn On/Off from On/Off node to Damage Volume

If you preview now, standing next to your barrel while destroying it will eliminate the player.

Make it sparkle

Place an Explosion node on top of the barrel

Connect Event: On Destroyed → Function: Play from Target Cylinder to Explosion

Hide target cylinder

Finally, to hide the target cylinder from the player, place a Set Visibility Node

Connect Event: Act On → Function: Visibility from Set Visibility Node to the Target Cylinder
