META is the meta-calculation contract that provides the Beat function for computing game values. It coordinates between RING and the power calculation chain.

  • Kind: Contract
  • License: Sharia
  • Solidity: ^0.8.21

  1. self — META
  2. DYSNOMIA
  3. MultiOwnable

Plain English Summary: META is the master calculator for the WORLD territory system. It provides the Beat function that determines the key values (Dione, Charge, Deimos, Yeo) used when you claim territory. The “Yeo” value is especially important - it defines how far from a QING you can code.

Real-World Analogy: META is like a zoning commission that determines property boundaries. When you want to claim territory, META calculates how far your claim can extend (Yeo/range) and what rewards you’ll get (Dione) based on your relationship with nearby venues.

How It Affects Your Gameplay:

  • Range limits - META’s Yeo output determines how far from a QING you can Code()
  • Reward calculation - Deimos influences how much VITUS you earn
  • WORLD integration - META’s Beat() is called during territory claiming

Players can call Beat(uint256) directly. Transaction 0x0569abb1a364305747a806070f6490d29ab2e21d4665e90a99f22e8bfac57007 succeeded canonically at block 27494314 from a wallet that was not a META or RING owner. The deployed execution path differs from this recovered source snapshot by routing the reaction through CHAN, so prerequisites should be checked against live state before preparing a transaction.

  • WORLD - Uses Beat for Code
function Beat(uint256 QingWaat) public returns (uint256 Dione, uint256 Charge, uint256 Deimos, uint256 Yeo) {
uint256 Omicron;
uint256 Omega;
QINGINTERFACE Qing = Ring.Pang().Zi().Choa().Sei().Chan()
.Xie().Xia().Mai().Qi().Zuo().GetQing(QingWaat);
// Get Ring Eta values
(uint256 Phoebe, uint256 Iota1, uint256 Chao, uint256 Charge1) = Ring.Eta();
// Get Push values
(Yeo, Omicron, Dione, Omega, Charge) = Ring.Pang().Push(QingWaat);
// Combine charges
Charge = Charge1 * Charge / Iota1;
// Calculate Deimos
Deimos = Xiao.modExp(Dione, Phoebe, Ring.Pang().Zi().Choa().Yuan(address(Qing)));
Yeo = Chao / Yeo;
}

The Yeo return value is used in WORLD.Code() to define the valid range around a QING’s position where players can code.
