Explosive Device Design Example

The Explosive device is a fun way to add action to any island.

In this design example, you'll explore a simple mechanic that you can use to add a bubbling visual effect to an explosive barrel that warns players splayers it's about to explode!

You can add this game mechanic to any game or experience to give it a little flash!

Devices Used

• 1 x Explosive device

• 1 x VFX Creator device

• 1 x Timer device

• 1 x Trigger (or other activating) device

Build Your Own

You will set up an explosive barrel and create a visual effect to go with it. Next, you'll set up a timer to control the timing of the blast, then add a trigger to set the whole mechanic in motion!

Place the Explosive Device

1. Place an explosive barrel on your island.

2. Customize the settings:

   

   Option	Value	Description
   Display Damage Numbers	On	Shows any damage dealt to the device by players.
   Collision During Games	Only When Visible	Device only has collision on during gameplay.

3. Make sure the Device Mesh is set to Barrel (the default setting).

Place a VFX Creator Device

When you place the VFX Creator device, be sure to place it on top of the barrel.

To place the device on top of the barrel, you may need to turn off the Drops option on the Create mode hotkeys menu.

Select an option, then use the Drops hotkey to toggle this On or Off.

This is a context-sensitive menu, which means options change based on your current actions.

1. Place the VFX Creator device.

2. Customize the settings:

   

   

   Option	Value	Description
   Enabled During Phase	None	Set to None because you will be using event binding to activate the device.
   Sprite Shape	Bubble	The fastest way to find this sprite is to click the arrow then use the search box.
   Sprite Size	0.4X	This reduces the size of the bubbles.
   Main Color	#00F471	This is hexadecimal code for green. This sets the main color for the bubbles used in this device design example. Feel free to select other colors — the colors do not affect gameplay, but can affect your mood if you pick colors you like a lot!
   Main Color Brightness	200	This intensifies the main color.
   Use Secondary Color	Yes	When set to Yes, you can add a secondary color for your bubbles.
   Secondary Color	#FFF000	A shade of yellow used in this device design example.
   Secondary Color Brightness	80	You boosted the brightness of the main color, but for the secondary color, you'll drop it a bit.
   Sprite Speed	10	This slows down the rise of the bubbles, giving them a more realistic movement.
   Effect Gravity	-10	Note that this is a negative number. Setting the gravity to a negative causes the effect to rise instead of fall.
   Keep Size	No	Sets whether the size of the sprite will change over time.
   Size Over Time	100	Sets the amount of change in size for the effect sprites.
   Loop Duration	10S	This is how long the effects will play when triggered.
   Time Between Loops	30S	Controls the time between multiple loops.
   Spawn Zone Shape	Point	Sets the shape for the area where the effects first appear.

Add a Timer Device

Time to set the timer! This will control the timing of the bubble blast.

1. Place a Timer device.

2. Configure the timer:

   

   Option	Value	Description
   Duration	3.0 Seconds	How long the timer will take to complete.
   Can Interact	No	The player cannot interact with the timer. Instead, the Trigger device will trigger it.
   Completion Behavior	Disable	When the timer finishes, it will be disabled.
   Visible During Game	Hidden	The timer should not appear during the game..
   Show on HUD	No	The timer will not display on the HUD.

Add a Trigger Device

The final device to place is the trigger. The player will interact with the trigger, so it needs to be within the player's sight.

1. Place a Trigger device.

2. Move to the next section to set the device binding for the trigger.

Bind Devices

Direct event binding is how you set triggers between devices. When you set an event on one device, the binding automatically updates on the function for the bound device.

1. Set the following events for the trigger. When a player engages with the trigger during the game, this will call the timer to start its countdown, and enable the VFX effect.

   

   Event	Device	Function
   On Triggered Send Event To	Timer Device	Start
   On Triggered Send Event To	VFX Creator	Enable

2. Set this event for the timer:

   

   Event	Device	Function
   On Success Send Event To	Explosive Device	Explode

3. Set the following function for the VFX Creator device. (Note that the Trigger binding is already there from the previous step.)

   

   Function	Device	Event
   Disable When Receiving From	Explosive Device	On Exploded

   This will disable the explosive after it explodes.
