Read component properties in Construction Script?

[danamaloma]

@Ren_D

1. I created a new component containing a variable.
2. Created a new blueprint.
3. Added a component to my blueprint.
4. My blueprint containing my component is placed on the scene.
5. On the stage, I changed the values of the variable, in the component inside the bluetooth.
6. In blueprint on the Construction Script, I read the value of the variable from the component.

I expect to get the value of the variable entered on the scene (MyVar=10)
I get the default value. (MyVar=0)

Tell me how to fix this problem?

Recommended approach (used in many games)

Instead of relying on blocking collision, use a Trigger Volume (Box/Sphere Overlap) and handle the behavior manually:

1. Detect entry into boundary

• Place a larger invisible volume where the “soft wall” starts.

• Use OnComponentBeginOverlap to detect when the player enters it.

2. Gradually reduce player control

• As the player gets closer to the edge, scale down their input or velocity.

• For example:

  • Map distance → speed multiplier (1 → 0)

  • This creates that “pushing against resistance” feel
    This is a known technique: mapping distance to movement limits instead of stopping instantly (Epic Developer Community Forums)

3. Apply opposite force (rubber band)

• When inside the volume, apply a force or movement offset back toward the center:

  • Direction = (center − player position)

  • Strength increases the deeper they go

4. Release behavior

• When player stops pushing, the force naturally pulls them back → gives that elastic feel

Alternative (simpler Blueprint logic)

A very common pattern suggested by UE devs:

• First phase: slow player to a stop (~1 second)

• Second phase: apply increasing force pushing them back

This creates a smooth 2–3 second interaction instead of a hard stop (Epic Developer Community Forums)

Implementation tips (important)

• Avoid pure blocking volumes → causes your “stuck” glitch

• Use overlap + manual velocity control

• Modify:

  • Max Fly Speed

  • or directly scale input axis

  • or use Add Force / Add Movement Input in reverse direction

• Use a falloff curve (Float Curve asset) for smoothness

• Clamp max pushback force so it doesn’t feel jerky

Bonus: “Star Fox feel”

For that classic Star Fox boundary:

• Use a camera-centered box

• Always push player toward screen center (not world center)

• Add slight camera shake or tilt when pushing → sells the effect

---

TL;DR

• No built-in UE5 feature for this

• Don’t use hard collision

• Use:
  Overlap Volume + distance-based slowdown + reverse force

• Think of it as a soft constraint field, not a wall
