Glossary

Sandbox terms explained in one sentence: asset, entity, role, rule, hash, epoch, weight, harvest, draft registry, watchdog and many more.

The vocabulary of the studio, the engine and the platform, in alphabetical order. Each definition links to the page that covers it in detail.

Asset
A reusable object of the game: voxel grid, primitive build or imported model. A document holds 96 at most; entities point at them. Learn more
Boolean operation
Union, subtraction or intersection of a primitive with the pieces listed before it in the same bone (op). Learn more
Claim
Collecting a settled epoch’s share for a game. The share goes to the game’s current creator, once, and only expires after 90 days. Learn more
Clip
A named animation: a duration, a loop and keyframe tracks per part. The runtime picks the clip from the state (idle, move, jump, hit, attack…). Learn more
Draft registry
The publishing mode while the contract is not deployed: your wallet signs the game’s hash and the platform lists it with a d-… id. Learn more
Entity
A thing placed in the world: an asset (or none, for a marker), a role, a position, a rotation, a scale and parameters. Learn more
Epoch
A 24-hour period counted from the contract’s deployment. Plays are counted per epoch, and each finished epoch is settled once. Learn more
Harvest
Contract function, callable by anyone, that pulls the token’s creator fees from Pons into the reward vault. Learn more
Hash (keccak256)
The keccak256 of the canonicalised document (sorted keys). The same game always has the same hash; it is what goes on-chain and what names the stored file. Learn more
HDRI
A high dynamic range panoramic image used as sky and environment lighting. The library offers 28. Learn more
HUD
The overlay on top of the game: score, timer, health, lives, coins, messages and chosen variables. Learn more
Mode
The kind of game (race, platformer, arena, runner, explore, capture the flag, tower defense): it provides controller, camera and win conditions. Learn more
Mood
A preset that applies sky, hour, fog, light, weather and post-processing at once (sunset, neon night, misty forest…). Learn more
Part
A rigid piece of an asset, with its pivot and an optional parent. Animation tracks move parts. Learn more
Pathfinding (A*)
How enemies and NPCs find their way on a navigation grid, around water and obstacles. Learn more
Pons
The Robinhood Chain token launcher where $SANDBOX will launch, with the Sandbox contract as creator fee recipient. Learn more
Primitive
A parametric shape (box, sphere, cylinder, cone, torus, capsule, extrude, lathe…) with a PBR material, the building block of mesh assets. Learn more
Remix
A copy of a published game opened in your studio. The document keeps the original game’s id in meta.remixOf. Learn more
Robinhood Chain
The blockchain where the game registry, the rewards and the token live. Learn more
Role
What an entity does: player start, coin, enemy, door, spawner, turret, waypoint… 23 roles in all. Learn more
Rule
No-code logic: an event, conditions on variables, actions. A rule can be set to fire only once. Learn more
Runtime
The engine that runs a game. It is the same on the studio’s Test step, on the game page and in previews. Learn more
SandboxGame
The type of the JSON document holding a whole game: meta, assets, terrain, entities, rules, variables, game rules, settings, HUD and scripts. Learn more
Settle
Settling a finished epoch, once every 24 hours: the operator writes the games, their weights and the amount to share on-chain. Learn more
Spawner
An entity that spawns an asset at a regular interval, within a radius, up to a simultaneous maximum and a total. Learn more
Tag
A free label put on an entity. Rules and scripts target entities by tag; * targets them all. Learn more
Template
A complete, playable game used as a starting point. There are eight; they never count for rewards. Learn more
Tip
ETH sent to a game, paid 100 % to its creator. Learn more
Trigger
A local entity event (touch, interact with E, stomp) that runs actions, once or every time, with an optional required key. Learn more
Variable
A named value (number, boolean or text) read and written by rules, triggers and scripts, and shown in the HUD if you want. Learn more
Voxel
A coloured cube in a grid. Voxel assets are grids of 8 to 64 per side with a colour palette. Learn more
Watchdog
The mechanism that terminates a stuck script Worker and starts a fresh one with the same scripts. Learn more
Waypoint
A path point. In tower defense, waves follow the waypoints toward your base. Learn more
Web Worker
The isolated thread where scripts run, with no access to the page, the DOM or the network. Learn more
Weight
The measure that splits a 24-hour epoch’s vault: sum over wallets of min(plays, 10), plus a tenth of anonymous plays capped at 20 % of the signed weight. Learn more
