Behaviors

A behavior is ready-made movement or logic you add to an object in one tap: walk and jump with the joystick, drive like a car, follow the player, spin, float up and down… Add one with Inspect → ＋ Add behavior.

＋ Add behavior

Each behavior card has a switch to turn it on/off and 🗑 to remove it. Events can do the same while playing (Enable/disable behavior) and change any setting (Set behavior setting); scripts use entity.setBehaviorParam('platformer', 'speed', 8). In expressions: Player.behavior("platformer", "speed").

🏃 Platformer

Walk with the joystick (or WASD / arrows) and jump with a button. Needs a dynamic Physics body — adding the behavior adds one that doesn’t tip over, and a Collider.

Setting	Default	What it does
Speed	5	Walking speed (m/s).
Jump strength	7	How high it jumps.
Jump button	jump	The touch button that jumps (see Touch controls).
Turn to direction	on	Face the way it moves.
Camera relative	on	“Up” on the joystick means away from the camera, not a fixed direction.
Animate	on	Play the model’s idle / walk / sprint / jump / fall clips automatically.

🕹️ Top-down movement

Move in 8 directions on the ground with the joystick — no jumping. For top-down, twin-stick and rolling-ball games. Works with or without a Physics body (with one, it pushes and gets blocked by things).

Setting	Default	What it does
Speed	5	Movement speed.
Turn to direction	on	Face the way it moves.
Camera relative	on	Joystick directions follow the camera.
Animate	on	Idle / walk / sprint clips automatically.

🏎️ Car

Drive with the joystick: up = gas, down = brake, then reverse, left/right = steer. Real ray-cast vehicle physics with suspension. Needs a dynamic Physics body.

Setting	Default	What it does
Speed	15	Top speed (m/s).
Acceleration	10	How fast it speeds up.
Steering	30	Largest steering angle (degrees).
Grip	1	Tyre grip. Lower = drifty, higher = sticky.
Brake	1	Braking strength.
Wheels	—	Which nodes of the car model are the wheels (they spin and steer). Tap to choose; mark the front ones.

Wheels are found automatically in models whose parts are named “wheel…” (like the Kenney car kit). Otherwise pick them in Wheels; without wheels it drives on 4 invisible wheels at the corners.

🎥 Camera follow

Put it on the camera: it smoothly follows a target.

Setting	Default	What it does
Target	Player	The object to follow.
Offset X / Y / Z	0, 6, 10	Where the camera stays, relative to the target (6 up, 10 behind).
Smoothing	5	Higher = snappier, lower = floatier.
Look at target	on	Keep pointing at the target.
Stay behind	off	Turn the offset with the target’s heading — a chase camera for cars and runners.

🔄 Rotate

Spins constantly — coins, fans, windmills, planets.

Setting	Default	What it does
Speed X / Y / Z	0, 90, 0	Degrees per second around each axis.

➤ Bullet

Keeps moving forward (its −Z direction) — bullets, arrows, rockets, moving obstacles. Spawn it facing the right way (e.g. Create object at the gun, then Set angle).

Setting	Default	What it does
Speed	10	Meters per second.
Gravity	off	Falls over time (arrows, cannonballs).

〰️ Wave (sine)

Smoothly moves back and forth forever — floating pickups, bobbing boats, moving platforms, pulsing lights.

Setting	Default	What it does
Property	y	What waves: x, y, z, angle, scale or opacity.
Magnitude	0.5	How far (meters; degrees for angle).
Period	2	Seconds for one full wave.

🎯 Follow target

Moves toward another object — chasing enemies, pets, homing missiles.

Setting	Default	What it does
Target	Player	What to follow.
Speed	2	Meters per second.
Stop distance	1	Stops this close.
Look at	on	Face the target.
Animate	on	Walk / idle clips automatically.

🗑️ Destroy when far

Removes the object when it falls or goes too far — keeps games with many bullets or spawned obstacles fast.

Setting	Default	What it does
Kill Y	−20	Destroyed when it falls below this height.
Max distance	200	Destroyed this far from the camera (0 = never).

✋ Draggable

The player can drag it with a finger — puzzles, sorting games, placing things.

Setting	Default	What it does
Axis	xz	xz = along the ground, xy = up/down and sideways (facing the camera), or a single axis x, y, z.
