Engine: Rust, whole numbers only Tick: 50 ms, 20 per second Coordinates: 18,000 units to one tile

The Clash Royale battle engine your bot plays in. It runs the whole match on your own machine. Most people use it through RoyaleGym and never call it directly.

An engine battle in the RoyaleViser viewer, 18 units on the board

Install

pip install "royalegym[all]"

That installs this engine and everything else. Use Python 3.12. Install has more.

Try it

import json, royalesim

b = royalesim.Battle(card_names=None, slot_of_k=[[0, 1, 2], [0, 1, 2]])
ids = {row[0]: i for i, row in enumerate(json.loads(b.catalogue_json()))}
deck = [ids[n] for n in ["Knight", "Archer", "Goblins", "Giant", "Musketeer", "Fireball", "Arrows", "Skeletons"]]
b.reset(seed=0, decks=[deck, deck], shuffle=1, start_tick=0, elixir_milli=[5000, 5000], tower_hp=None, spawns=[])
b.step([], 100)                                          # nobody can play in the opening seconds
r = b.step([(0, 0, 9000 * 18, 10000 * 18)], 20)         # blue plays its first card, then 20 ticks pass
print(json.loads(b.state_json())["tick"], royalesim.DEPLOY_REASONS[r[0][1]])   # 120 OK
