Level design
A level is a sequence of intentional experiences delivered through space.
Good level design is a process: define the metrics movement is built on, block
out geometry with primitives, play it, then dress it — never the reverse. This
skill is the engine-neutral practice; use godot-tilemap/unity-tilemap-2d to
lay out 2D grids and gridmaps for 3D.
When to use
- Use to plan a level's structure: critical path, pacing, gating, encounters, and where the player learns vs is tested.
- Use the blockout → test → iterate → dress workflow to build a level that plays well before any art exists.
- Use to derive level metrics from the character's movement so geometry is reachable and fair.
When not to use: to generate levels algorithmically, use procedural-gen
(authored and procedural design are complementary). For the engine's tile/grid
painting tools, use godot-tilemap / unity-tilemap-2d. For the movement
abilities the metrics come from, that's the engine movement skill + input-systems.
Core workflow
- Derive metrics first. Measure the character: max jump height and distance, run speed, reach, camera range. Every gap, ledge, and corridor is sized in these units. Lock them before building geometry.
- Blockout (whitebox/greybox). Build the whole level from untextured primitives at correct scale. Validate flow, sightlines, and reachability while changes are cheap. No art yet.
- Define the critical path (start → goal) and the golden path you expect most players to take. Layer optional/secret paths off it.
- Pace the experience. Alternate tension and rest in a deliberate curve; don't run combat-combat-combat. Give the player room to breathe and to anticipate.
- Teach, then test. Introduce each mechanic in a safe space, let the player practice, then test it under pressure. Difficulty rises in a sawtooth, not a straight line.
- Gate with intent. Use locks/keys, abilities, and one-way drops to control order and pacing; guide with light, lines, and landmarks rather than walls.
- Playtest and iterate. Watch real players: where do they get lost, stuck, bored, or killed unfairly? Fix the blockout; only dress when it plays well.
Patterns
1. Player metrics drive every dimension
# Measure the character ONCE, then size geometry in these units. If the jump
# changes, gaps must be re-derived — never eyeball reachability.
const RUN_SPEED := 240.0 # px/s (or m/s in 3D)
const MAX_JUMP_H := 96.0 # peak height of a full jump
const MAX_JUMP_DIST := 200.0 # horizontal distance of a running jump
const SAFE_GAP := MAX_JUMP_DIST * 0.7 # comfortable, not pixel-perfect
const HARD_GAP := MAX_JUMP_DIST * 0.95 # a deliberate skill check
# Build platforms so required jumps use SAFE_GAP; reserve HARD_GAP for optional reward.
A reachable level falls out of honest metrics. A platform placed MAX_JUMP_DIST + 1 away is impossible; one at SAFE_GAP is fair. Keep these constants beside the
level data so designers and code agree.
2. Encounter / pacing as data (a tension timeline)
# Author the level as a sequence of beats with an intended intensity (0..1).
# This makes the pacing curve explicit and reviewable before you build rooms.
const BEATS := [
{ "room": "entry", "type": "teach", "intensity": 0.1 },
{ "room": "hall_1", "type": "combat", "intensity": 0.5 },
{ "room": "vista", "type": "rest", "intensity": 0.1 }, # breather + reward
{ "room": "gauntlet", "type": "combat", "intensity": 0.8 },
{ "room": "save_room", "type": "rest", "intensity": 0.2 }, # before the boss
{ "room": "boss", "type": "climax", "intensity": 1.0 },
]
# Read the intensity column top-to-bottom: it should rise overall but dip for rests
# (a sawtooth), never flatline high. Drive spawns/music intensity from this.
3. Gating and the critical path (a small graph)
# Model the level as rooms + gated connections. Validate that the goal is
# reachable with the keys/abilities the player can actually obtain in order.
const ROOMS := {
"entry": { "exits": [ { "to": "hall_1" } ] },
"hall_1": { "exits": [ { "to": "vista", "needs": "double_jump" },
{ "to": "side_room" } ] }, # optional branch
"side_room": { "exits": [ { "to": "hall_1" } ], "grants": "double_jump" },
"vista": { "exits": [ { "to": "boss", "needs": "red_key" } ] },
}
# Validation (do this!): from "entry", can the player reach "boss" given that
# "double_jump" is granted in "side_room" before "vista" requires it? A flood
# fill that only traverses an exit when its `needs` is already satisfiable
# proves the critical path isn't soft-locked.
Pitfalls
- Dressing before it plays. Detailing a blockout you haven't validated wastes the most expensive work on a layout you'll change. Greybox and test first.
- Geometry that ignores metrics: gaps the jump can't clear, ledges below reach, corridors narrower than the camera needs. Size everything in player units.
- Flat pacing. Wall-to-wall combat (or wall-to-wall calm) numbs the player. Alternate tension and rest; place a breather and a save before the climax.
- Testing a mechanic before teaching it. Players meet a hazard for the first time in a lethal spot. Introduce safely, let them practice, then test.
- Soft-locks and dead ends. A gate needs an ability/key obtainable only past the gate. Validate the critical path's key/ability order, not just connectivity.
- No readability / guidance. Players get lost when nothing draws the eye. Use light, leading lines, color, and landmarks to point toward the path.
- One-way drops with no signposting strand or surprise players. Telegraph irreversible moves.
- Confusing procedural with authored. Generation gives variety, not
authored pacing. Use
procedural-genfor variety; hand-author for intent.

# Level design
A level is a **sequence of intentional experiences** delivered through space.
Good level design is a *process*: define the metrics movement is built on, block
out geometry with primitives, play it, then dress it — never the reverse. This
skill is the engine-neutral practice; use `godot-tilemap`/`unity-tilemap-2d` to
lay out 2D grids and gridmaps for 3D.
## When to use
- Use to plan a level's structure: critical path, pacing, gating, encounters,
and where the player learns vs is tested.
- Use the **blockout → test → iterate → dress** workflow to build a level that
plays well before any art exists.
- Use to derive level **metrics** from the character's movement so geometry is
reachable and fair.
**When *not* to use:** to *generate* levels algorithmically, use `procedural-gen`
(authored and procedural design are complementary). For the engine's tile/grid
painting tools, use `godot-tilemap` / `unity-tilemap-2d`. For the movement
abilities the metrics come from, that's the engine movement skill + `input-systems`.
## Core workflow
1. **Derive metrics first.** Measure the character: max jump height and distance,
run speed, reach, camera range. Every gap, ledge, and corridor is sized in
these units. Lock them before building geometry.
2. **Blockout (whitebox/greybox).** Build the whole level from untextured
primitives at correct scale. Validate flow, sightlines, and reachability while
changes are cheap. No art yet.
3. **Define the critical path** (start → goal) and the **golden path** you expect
most players to take. Layer optional/secret paths off it.
4. **Pace the experience.** Alternate tension and rest in a deliberate curve;
don't run combat-combat-combat. Give the player room to breathe and to
anticipate.
5. **Teach, then test.** Introduce each mechanic in a safe space, let the player
practice, then test it under pressure. Difficulty rises in a sawtooth, not a
straight line.
6. **Gate with intent.** Use locks/keys, abilities, and one-way drops to control
order and pacing; guide with light, lines, and landmarks rather than walls.
7. **Playtest and iterate.** Watch real players: where do they get lost, stuck,
bored, or killed unfairly? Fix the blockout; only dress when it plays well.
## Patterns
### 1. Player metrics drive every dimension
```gdscript
# Measure the character ONCE, then size geometry in these units. If the jump
# changes, gaps must be re-derived — never eyeball reachability.
const RUN_SPEED := 240.0 # px/s (or m/s in 3D)
const MAX_JUMP_H := 96.0 # peak height of a full jump
const MAX_JUMP_DIST := 200.0 # horizontal distance of a running jump
const SAFE_GAP := MAX_JUMP_DIST * 0.7 # comfortable, not pixel-perfect
const HARD_GAP := MAX_JUMP_DIST * 0.95 # a deliberate skill check
# Build platforms so required jumps use SAFE_GAP; reserve HARD_GAP for optional reward.
```
A reachable level falls out of honest metrics. A platform placed `MAX_JUMP_DIST +
1` away is impossible; one at `SAFE_GAP` is fair. Keep these constants beside the
level data so designers and code agree.
### 2. Encounter / pacing as data (a tension timeline)
```gdscript
# Author the level as a sequence of beats with an intended intensity (0..1).
# This makes the pacing curve explicit and reviewable before you build rooms.
const BEATS := [
{ "room": "entry", "type": "teach", "intensity": 0.1 },
{ "room": "hall_1", "type": "combat", "intensity": 0.5 },
{ "room": "vista", "type": "rest", "intensity": 0.1 }, # breather + reward
{ "room": "gauntlet", "type": "combat", "intensity": 0.8 },
{ "room": "save_room", "type": "rest", "intensity": 0.2 }, # before the boss
{ "room": "boss", "type": "climax", "intensity": 1.0 },
]
# Read the intensity column top-to-bottom: it should rise overall but dip for rests
# (a sawtooth), never flatline high. Drive spawns/music intensity from this.
```
### 3. Gating and the critical path (a small graph)
```gdscript
# Model the level as rooms + gated connections. Validate that the goal is
# reachable with the keys/abilities the player can actually obtain in order.
const ROOMS := {
"entry": { "exits": [ { "to": "hall_1" } ] },
"hall_1": { "exits": [ { "to": "vista", "needs": "double_jump" },
{ "to": "side_room" } ] }, # optional branch
"side_room": { "exits": [ { "to": "hall_1" } ], "grants": "double_jump" },
"vista": { "exits": [ { "to": "boss", "needs": "red_key" } ] },
}
# Validation (do this!): from "entry", can the player reach "boss" given that
# "double_jump" is granted in "side_room" before "vista" requires it? A flood
# fill that only traverses an exit when its `needs` is already satisfiable
# proves the critical path isn't soft-locked.
