Learn Rush Duel Scripting

Build a Rush card using the same effect fundamentals as the main learning path, then add the Rush library's requirements, rules, and summon procedures.

1 · First effectRequirement to resolutionWalk through Mystic Dealer, callback factories, drawing, and the Rush rules layer.2 · Resolve an actionChoose cards and change statsSeparate optional actions from legality checks and give temporary effects a lifetime.3 · Advanced mechanicsMaximum, Fusion, RitualConnect the database, monster procedure, and effect that performs the summon.4 · Read real cardsRush examplesCompare full imported scripts with their card text and helper calls.

Your starting point	Next step
New to Lua	Lua Essentials, then Script Structure.
Know normal YGOPro scripts	Rush Duel Scripting; focus on helper shapes and shared rules.
Need a particular helper	Rush function reference and the Rush format in Script Explorer.
Choosing monsters or giving temporary ATK/DEF	Follow Rush selection and actions.
Card loads but Rush behavior is missing	Check database and runtime wiring.
Implementing a Maximum or Ritual card	Follow Rush summon procedures and its source examples.

Keep Three Questions Separate

1. Is this Rush card data? Check the database, ID, and type flags.
2. Has the duel loaded Rush rules? The game must initialize the Rush runtime.
3. Does this particular effect work? Trace its condition, cost, target, and operation.

A Rush pool flag does not load RD, and a working draw effect does not prove that the duel loaded the Maximum, Legend, or timing behavior. The lessons mark which layer is responsible and give observable checks for each example.

Ready To Move On?

After the first lesson, explain why RD.CostSendHandToGrave(...) is called while building the script but RD.Draw() is called during resolution. After the selection lesson, explain why RD.CanSelectAndDoAction belongs in the operation and why an action callback with no return does not produce a success count. After the summon lesson, explain why a Maximum side piece uses EFFECT_TYPE_XMATERIAL and why that does not make it an Xyz Monster.

Return to the lesson library for shared topics such as Groups, reset flags, card movement, and debugging.
