First person 4d geometry game engine, written in Rust, inspired by www.urticator.net. Under development; the current version amounts to a demo.

There is a 3d and a 4d mode, toggled with backspace.

Your choice of FPS-like controls or tank controls, toggled with M

Move with WASD in 3d and QWEASD in 4d. Mouse controls will be familiar in 3d. In 4d, moving the mouse will turn the player along the two lateral axes. When holding SHIFT, moving the mouse will spin the lateral axes and allow the player to look up and down.

• W/S : Move forward/back

• A/D : Turn left/right (yaw)

• I/K : Look up/down (pitch)

• Q/E : (In 4d) turn other left/right

• SHIFT+Q/E : Rotates lateral axes in 4d

• Holding down ALT causes the player to slide along an axis instead of rotate.

• Backspace Switches between 3d/4d mode

• C Toggles clipping

Edit mode can be enabled from the config file. Click on an object to select it.

• F : Freely manipulate object with player controls

• T : Translate mode

• R : Rotate mode

• Y : Scale mode

• M : Confirm change and exit edit mode

• \ : Discard change and exit edit mode

Use - 1, 2, 3, 4 to select axes, and scroll or move the mouse or to manipulate the selected object. Translation requires at least one axis, and rotation requires 2 or 4. Holding ~ snaps movement to discrete intervals.

• SHIFT+~: Snap object to closest half-integer grid point.
• ,: Reset object orientation and scale.
• /: Delete object
• ;: Duplicate object
• .: Create cube

• config file
• fuzz texture
• skybox
• edit mode

• Level design and spatial challenges
