It does not work yet just some proof of concept. But the code might be interesting so I put it up.

I found interesting private method named CreateSystemDependencyList in ScriptBehaviourUpdateOrder.cs so I tried using reflection and take List<InsertionBucket> out to experiment.

Each item is a system and all of its before and after systems. I want to visualize this as a graph. My idea is to start from those without afters as root nodes on the first column.

• Very messy code, just screw around for a quick result.
• Barriers are considered root nodes because they don't have any update afters. But in the actual game barrier runs after it gets a command from some system that runs way later.
• I don't know graph theory, how to arrange a graph nicely based on previous/next relationship between nodes without any depth assigned on them? Basically I tried to calculate depth for each one but those depths are bad.
• The traversal code put nodes at some depth way down below. (I intended for each column to start at the top)
• There are some lines that travels backward to the previous column.
• Some line goes under nodes and skips depth.
• The lines are so messy that it barely provide any benefits from looking at them.
• Some "reactive" type system are at the first column. In the actual code they does not have any before/afters so they do go to the first column, but the intention for these systems is to react after some other system put out a message. Before/after dependency could not account for this. (No automatic system could account for this, I think.)
