🎯 Devlog 3 – Designing Intuitive Drag-and-Drop for Movement Keys

Control is a Resource

The core mechanic depends on letting players grab, place, and retrieve their movement keys smoothly — so the drag-and-drop interaction had to feel natural and intentional.

Making Dragging Feel Right

I wanted players to feel in control, not frustrated by slippery or imprecise UI. Some key design decisions:

  • Click and hold to drag — this prevents accidental placements from a quick tap.

  • Visual feedback during drag — a translucent “ghost” platform shows exactly where the key will land.

  • Snap-to-grid positioning — placed keys align neatly to the world grid for predictability and easier platforming.

Validating Placement

To avoid frustration, keys can only be placed on valid ground areas. The system checks:

  • Does the position collide with solid surfaces?

  • Is the space free from other platforms or obstacles?

If a player tries to drop a key in an invalid spot, it snaps back to the UI bar — no penalty, just a gentle nudge to try again.

Reclaiming Keys

Retrieving keys needed to be just as simple and satisfying:

  • Clicking a key platform in the world instantly removes it and unlocks the corresponding input.

  • Pressing Shift lets the player reclaim all keys at once, a handy “panic button” if stuck.

  • Visual and audio feedback confirms the reclaim action.

Preventing Exploits and Edge Cases

Even simple mechanics can be twisted. Some cases I had to carefully design around:

  • Preventing infinite jumps by spamming platforms below the player.

  • Disallowing placing keys inside walls or unreachable places.

  • Handling mid-air retrievals gracefully, without breaking player movement.

These constraints preserve challenge without compromising player freedom.

The Result: A Satisfying Control Economy

The drag-and-drop interaction ties the whole system together, making the player feel the cost of each movement — and the reward of careful planning and reclaiming.

It transforms movement from a given to a resource management challenge — exactly what this jam’s theme inspired me to create.

What’s Next?

Next time, I’ll talk about polishing feedback — sounds, visuals, and small touches that make the resource mechanic emotionally engaging.
