ArcCast — Trajectory & Landing Preview

Unreal Engine 5.8 · one runtime module · Win64

The throw arc you can actually ship: bounce-chained trajectory prediction with a landing verdict, a splash ring conformed to the geometry, and occlusion-aware drawing — on UCanvas, so it survives a Shipping build.

The engine already predicts the path. It just cannot draw it: the only renderer is DrawDebugLine, and ENABLE_DRAW_DEBUG is 0 in Shipping. ArcCast draws through AHUD instead — no material, no mesh, no Niagara, no asset of any kind.

ArcCast does not throw anything. No projectile, no damage, no replication. It shows where the thing your game is about to launch would end up.

Quick start

  1. Copy ArcCast/ into your project's Plugins/ folder, restart the editor.
  2. Add the ArcCast component to the actor that aims. Attach it to the hand or the muzzle.
  3. Leave Profile empty — the built-in Grenade profile is used, so an arc appears immediately.

The arc is visible in PIE and in a packaged build through whatever HUD class you already have, and in the editor viewport with no play session — for that last one press G for Game View, because the editor path hangs off the engine's Game show flag.

To throw for real, hand Get Launch Location and Get Launch Velocity to your spawn — then the projectile follows the arc that was drawn.

What it does past the engine's own prediction

  • Bounce chain — the simulation continues past the first hit; later stretches draw thinner and fainter.
  • Landing verdict — Valid / TooSteep / Blocked / OutOfRange / NoGround, colouring the arc and broadcast as an event. With the navigation check on, it is a teleport target indicator.
  • Conformed splash ring — every ring point is probed onto the surface, so the ring lies on stairs and slopes instead of hovering through them.
  • Occlusion-aware drawing — hidden stretches are drawn faint and dashed, not removed.
  • Prediction with no drawing — Predict Arc returns the whole result and draws nothing.

ArcCast — Trajectory & Landing Preview
Unreal Engine 5.8 · one runtime module · Win64
The throw arc you can actually ship: bounce-chained trajectory prediction with a landing verdict, a
splash ring conformed to the geometry, and occlusion-aware drawing — on UCanvas, so it survives a
Shipping build.
The engine already predicts the path. It just cannot draw it: the only renderer is DrawDebugLine,
and ENABLE_DRAW_DEBUG is 0 in Shipping. ArcCast draws through AHUD instead — no material, no
mesh, no Niagara, no asset of any kind.
ArcCast does not throw anything. No projectile, no damage, no replication. It shows where the
thing your game is about to launch would end up.
Quick start
  1. Copy ArcCast/ into your project's Plugins/ folder, restart the editor.
  2. Add the ArcCast component to the actor that aims. Attach it to the hand or the muzzle.
  3. Leave Profile empty — the built-in Grenade profile is used, so an arc appears immediately.
The arc is visible in PIE and in a packaged build through whatever HUD class you already have, and
in the editor viewport with no play session — for that last one press G for Game View, because the
editor path hangs off the engine's Game show flag.
To throw for real, hand Get Launch Location and Get Launch Velocity to your spawn — then the
projectile follows the arc that was drawn.
What it does past the engine's own prediction
  • Bounce chain — the simulation continues past the first hit; later stretches draw thinner and
fainter.
  • Landing verdict — Valid / TooSteep / Blocked / OutOfRange / NoGround, colouring the
arc and broadcast as an event. With the navigation check on, it is a teleport target indicator.
  • Conformed splash ring — every ring point is probed onto the surface, so the ring lies on
stairs and slopes instead of hovering through them.
  • Occlusion-aware drawing — hidden stretches are drawn faint and dashed, not removed.
  • Prediction with no drawing — Predict Arc returns the whole result and draws nothing.
