Slingshot (Ungrounded)

WORK IN PROGRESS

DESCRIPTION

The breakthrough was realizing the normal ground/perch slingshot is a valid internal state-machine transition. The game already knows how to do the move perfectly, but it refuses to select that transition while Spider-Man is airborne, swinging, or falling.

So the mod does not invent slingshot from scratch. It records a real successful ground slingshot transition, then reuses that valid transition later when the game normally rejects it.

That is why v0. 1 works.

The Core Discovery

The game has a traversal transition system. When you press LT+A / LT+Cross, the game asks something like:

“Given the current player state, input, target data, and event data, is there a valid transition?”

On the ground or on a perch, the answer is yes. The selector returns a slingshot plant event.

In the air, the answer is usually no. The input happens, but no valid slingshot transition event gets returned.

So the “gate” was not the controller input. It was the transition selector refusing to produce the normal slingshot event outside approved states.

What We Hooked

The working mod watches the normal game transition path instead of replacing the whole move.

Important runtime functions we identified:

• []SelectTransition at 0x3681230[/]

  []ProcessTransitions at 0x3682170[/]

  []BuildTransition at 0x367E140[/]

  []post-transition helper at 0x3680DB0[/]

  []game allocator at 0x2AF8550[/]

  []HeroStateSlingshotPlant constructor at 0x1312140[/]

  []HeroStateSlingshotPlantLocal constructor at 0x13139C0[/]

Those hooks let the mod see when the real slingshot is built, cache the event, and later feed that event back into the normal transition system.

What “Recording” Actually Means

It is not recording animation frames. It is not recording button presses. It is not recording controller input.

It records the game’s internal slingshot transition payload:

• []event bytes[/]

  []event type/hash data[/]

  []transition target pointer[/]

  []transition manager/self pointer[/]

  []flags[/]

  []value/timing field[/]

  []plant-state constructor arguments[/]

That is why this approach is powerful. We are borrowing the game’s own valid transition packet.

Installation:

• []Load into Overstrike[/]

  []REQUIREMENT  PLAYER IS REQUIRED TO PERFORM A NORMAL SLINGSHOT (FLAT SURFACE) [/]

   HOW IT WORKS

  []The hooks detect the real HeroStateSlingshotPlant / HeroStateSlingshotPlantLocal event.[/]

  []The mod copies that valid event data into memory.[/]
