Mega Tree API

Code generator

Fill the form, get a compiling Mono plugin, the csproj block and the cost table your players will actually pay.

Everything happens in your browser - nothing is uploaded. What you type is kept in localStorage so the page survives a refresh.

The output targets Mono and BepInEx 5: BaseUnityPlugin, Awake(), netstandard2.1. If you paste it into a Supermarket Simulator project it will not compile, and that is on purpose.

Your mod

Plugin guid The same string as in [BepInPlugin].

Sub-tab name Shown inside the Mods tab. Cut at 18 characters.

The node

Node id Lower case, prefix.name. Never change it after release.

Display name

Levels

Sort order Column position inside your sub-tab.

Sell-back rate 0 to 1. Leave at 0.5 for the tree default - the line is only emitted when you change it.

Price

Pricing

Base cost (level 1)

Cost multiplier 1.8 is the API default.

What the game itself charges

The player starts with $400. A store expansion is $600 at level 1 and about $80,000 for the whole thing - the largest sink in the game. Mega Tree's own cheapest line starts at $250 a level, and its most expensive node is $60,000.

Icon and text

Icon

Which built-in See them rendered on Icons.

Effect text C# interpolation. {lvl} is the 1-based level.

Gate (optional)

Locked until

Store level for level 1 (0 = no requirement)

Added per level after that

Scale

This is the game's own player level, the one that gates hiring and store growth. Asking for a number nobody reaches hides your node from nearly everyone. Leave both at 0 for no requirement at all - that is the default and it is a perfectly good choice.

Checks

Output

The effect is still yours

The generated plugin compiles and puts a node in the tree, but the bottom of the file is a commented-out patch, not a working effect. What the level does is the one part no generator can write for you. Events covers the three shapes it can take.
