Causality

An an Owlbear Rodeo extension for automating what happens next.

Causality lets Game Masters link causes and effects between tokens — so hidden traps spring, doors open, or any other domino effect happens automatically.

Features

• ⚡ Drag-and-drop interface for defining Cause ➜ Effect chains
• 🖇️ Combine multiple causes with AND / OR logic
• 🔄 Chain causalities together for Rube-Goldberg moments
• 🖱️ Dedicated Causality Move Tool so collisions can fire while you drag

How to use:

Step 1:

Add tokens to Causality.

Step 2:

Set one or more tokens as a "Cause"

A causality can have more than one cause. All or some (depending on whether they have AND or OR relationships) cause conditions must be met before a causality triggers.

Step 3:

Pair one or more tokens as an "Effect" to the "Cause(s)"

Step 4 (optional):

Chain more Causalities together!

Step 5:

Trigger the causality (or causalities). Reset them to start over.

IMPORTANT: If you want a collision to trigger while you're moving a token, you must be using the Causality Move Tool.

Collision modes explained

• There are both "Is Collided Into" and "Is Covered" cause conditions. When only using one cause in a causality, they appear to behave the same. However, if you are using multiple causes - the difference becomes more clear:

"Is Collided Into"

• If you have two causes in a causality with an AND relationship and they are both using this trigger type, a token can bump into one, move away from it, then bump into the other, and the causality will trigger.

Example: An adventurer finds and pulls levers as they traverse a dungeon. As they reach and pull the final lever, a hidden passage is revealed.

"Is Covered"

• If you have two Causes in a causality with an AND relationship and they are both using this trigger type, a token must stay over each before the causality triggers.

Example: Two adventurers must each stay standing on a pressure plate, before a hidden passage is finally revealed.

FAQ

Collisions don’t fire while I drag a token

• Make sure you’ve selected the Causality Move Tool (you can hit C on your keyboard as a shortcut to get to it). Collisions only update during movement when this tool is in use.

My token still isn't triggering a collision

• Even if that token isn't connected to a cause or effect, it must still first be added to Causality before it can be used to trigger collisions.

Thanks for checking out Causality! I made this because I wanted a way for hidden traps to appear automatically if one of my players moved their token into it. And then down the rabbit hole I went. Now we have this. 🙃
