Basics

An orange cube casting a soft shadow on a dark grey floor, lit from the upper left, seen from slightly above.

Hello cube

The smallest complete app: a light rig, a ground plane and a spinning cube.

Gamepad

Rendering

A detailed metal spaceship crossing the frame nose-down, seen from slightly below and in front: a warm key light picks out its worn hull plating, a rim light behind it burns the wing edges, its engines glow, and behind it a faint pool of light falls away to black at the corners.

Physically based rendering

The ignifx ship under image-based lighting, with bloom and ACES tone mapping.

Mouse
Touch
Gamepad

Seven grey shapes — a box, a sphere, a cylinder, a capsule, a torus, a cone and a slab — standing in two rows on a lit grid floor, with the cylinder at the centre of the frame picked out in orange.

Picking

Click to select: the GPU pick and the CPU raycast, at the same pixel.

Mouse

Post-processing

Ten emitters on a near-black floor: a back row of five small cubes running from a white-hot glow on the left to a plain blue one on the right, and a front row of five spheres running from near-black on the left to a glowing amber on the right.

Bloom

Emissive surfaces bleed light; threshold, weight, kernel and scale.

Lighting

Five pale primitives on a dark grid floor, lit from the upper left by a warm sun whose arrow gizmo hangs above them, with a blue point light orbiting inside a wide range ring and an orange spot light throwing a visible cone across the right of the frame.

Light types

Directional, point, spot and hemispheric, each drawn with a gizmo you can see.

Mouse
Touch
Gamepad

A sphere, a torus, a box and a capsule standing on a pale grid floor in daylight, each with a soft shadow stretching to the right, and a line of five pillars receding into the distance with shadows of their own.

Shadows

PCF, ESM and cascades over a long floor, with the map size, the biases and the distance live.

Mouse
Touch
Gamepad

Two staggered rows of spheres on a dark studio floor: seven metal ones in front running from a mirror that reflects the studio's softboxes to a matte grey, and seven blue painted ones behind them doing the same.

Image-based lighting

Three prefiltered environments, switched at runtime, with rotation and blur.

Mouse
Touch
Gamepad

A leather and cloth corset on a dressmaker's stand, lit from above on a dark studio floor, with a row of six glowing amber spheres behind it climbing from near-black to a pale rolled-off yellow.

Tone mapping and exposure

Standard, ACES, Neutral and none, with exposure and contrast, flipped A against B.

Models

A wooden street lamp with a glass lantern hanging from its arm, standing on a dark grid floor and casting a long soft shadow to the right.

Model loading

Load a glTF, watch it arrive, swap it for another, and hand the memory back.

Mouse
Touch
Gamepad

A six-by-six grid of spheres on a dark blue-grey ground: mirror-like spheres reflecting two soft studio panels along the bottom row, evenly diffuse ones along the top, pale plastic on the left and dark metal on the right.

Roughness and metalness

Thirty-six spheres from one mesh: metalness across, roughness up, every value live.

Mouse
Touch
Gamepad

A low-polygon orange fox at full stretch mid-run, fore legs forward and hind legs back, on a dark grid floor with its shadow beneath it.

Skinned animation

A rigged fox with three clips: pick one, blend two, change the rate, drag the playhead.

Mouse
Touch
Gamepad

2D

A pixel-art village seen from above: a wide dirt lane crossing the frame with a spur running north, red and grey cottages with tiled roofs along it, autumn and pine trees, mushrooms and a fenced paddock, and a small villager in a red tunic standing on the lane.

Tilemap

A Tiled map in three layers, drawn a chunk at a time, with a villager walking it.

Sprite animation

One atlas, four clips, a mirrored walk and a speed dial.

Mouse

Physics

A settled pile of dark orange crates, teal balls and sand-coloured capsules resting on a grid floor inside a low kerbed pit, lit from the upper left and casting soft shadows.

Physics playground

Drop boxes, spheres and capsules into a pit; change the surface they land on.

Mouse

Keyboard
Gamepad

An orange capsule standing half way up a pale 30-degree ramp that leads to a raised platform, with a much steeper dark ramp beside it, on a grid floor.

Character controller

A capsule that walks up a 30° ramp, refuses a 60° one, and jumps.

Keyboard

Touch
Mouse

A side-on pixel-art platformer level at dusk: a grassy earth floor with a dusk-blue pit cut through it on the left, a small blue-suited runner standing beside a flight of three low grassy steps, and two rows of wooden planks floating above and to the right.

Platformer controller

Ramps, low steps, one-way planks and coyote time on a kinematic character controller.

Keyboard
Gamepad
Touch

Nine wooden crates stacked three by three on a strip of grassy earth against a dusk-blue background, with a gold coin resting on the ground either side of them.

2D physics

Stack crates, roll coins into them, and watch Rapier take the tower apart.

Mouse
Touch

Gameplay

A pale blocky figure seen from behind and above, standing on a grey tiled floor inside a walled yard at dusk. A wall runs across the yard ahead of it with a dark doorway in it, and a shorter wall stands close on the left, throwing a long shadow across the floor.

Third-person

A character controller and an orbit camera that will not clip through a wall.

Keyboard
Mouse
Gamepad
Touch

A low-poly orange fox mid-stride on a grey tiled floor at dusk, front legs reaching forward and back legs pushing off, its tail streaming behind it and its shadow falling to the left.

Animator

A state machine with a blend tree, a trigger and animation events, all in one document.

Input

A small orange rover with four black wheels and a dark canopy stands on a grey grid floor in front of a wide dark instrument panel on two legs. The panel carries a cluster of unlit key caps on the left, two round dials with a dot at the centre of each, two narrow vertical tracks, four square lamps, and a row of small status lamps along the bottom, four of them lit green and one orange.

Input actions

Every device and every action, live: one document binds them, a board shows what they resolved.

Four dark plinths stand in a row on a grey grid floor, each capped with a bright orange block, and an orange ball rests on a long dark track in front of them.

Rebinding

Press a control, rebind an action, and keep it: the override is saved and survives a reload.

Audio

Three coloured faders — orange, cyan and amber — stand in a row on a dark grid floor, with a fourth green fader raised behind them and a pale rail linking all four. Five round pads sit across the front of the rig, one brown, three teal and one olive, and a thin amber ring is drawn on the floor around the desk.

Audio mixer

A bus tree with faders: one-shots on SFX, a loop on Music, and the autoplay lock in plain sight.

UI

Three copper shapes turning on a grid floor, with an orange pixel-font score reading SCORE 001200 in the top-left corner and a small readout panel below it listing the overlay's scaling mode, unit, size and scale.

UI overlay

A HUD, a dialog and toasts in HTML, over a scene you can still see.

Mouse
Keyboard
Touch
Gamepad

Platform

A ring of small blue capsules orbiting a lit orange pylon on a grid floor, with the ignifx devtools overlay docked down the left of the frame: a strip of nine tabs above an Inspector listing the Director entity's transform and its wave, spawned, alive and score fields.

Devtools overlay

The overlay, open on arrival, with a wave counter to watch.

Mouse

A pixel-art dusk landscape: a hill and a treeline behind a grass-topped dirt tilemap, a wooden plank and a brick platform with gold coins hanging above them, the character standing on the left, and a chip in the top corner that reads No coins.

Side-scrolling 2D game

Three parallax bands, a tilemap with slopes and one-way platforms, coins, and a pixel-perfect camera.

Keyboard
Gamepad
Touch
Mouse

A grey tiled courtyard ringed by dark panelled walls under a pale sky: the rigged character stands in the middle among scattered wooden crates, three beacon posts sit around the floor, and a chip in the top corner reads the player's speed and the companion's distance.

Mouse

A first-person view across a grey tiled room ringed by dark panelled walls: blue-grey crates and three pedestals stand ahead, a small crosshair sits at the centre of the frame, the view model and its teal prop fill the bottom corner, and a chip in the top corner reads that no pedestals are lit and nothing is in reach.

First-person 3D game

Walk, sprint, crouch and jump with pointer lock, a view model on the hand, and things to push.
