XML Level Code Cleaner & Syntax Optimizer
Repair broken level code, eliminate orphan joint crashes, auto-repair missing XML tags, and compact bloated coordinate floats to shed up to 60% of file size with 0ms client-side latency.
Missing closing </levelXML> tag. Automatically appended.
Purged 1 zero-dimension/invisible shapes to prevent Box2D inertia singularities.
Purged 1 out-of-bounds shapes beyond Box2D coordinate limits (> 50,000m).
Deduplicated 1 redundant static stacked shapes to save memory and draw calls.
Purged 1 orphan joints referencing non-existent body IDs to prevent game crashes.
Clamped 1 high-speed joint motors to 35 rad/s to eliminate wall-tunneling glitches.
⚙️Happy Wheels LevelXML Engine Architecture & Optimization Secrets
Happy Wheels runs on an ActionScript/WebGL port of the Box2D physics engine. When a level contains more than 250 dynamic interactive shapes (i="t"), the collision narrowphase scales quadratically, dropping the framerate below 30 FPS regardless of CPU strength.
If an author deletes a shape in the editor without first deleting connected joints, the joint retains dead pointers to bodyA or bodyB. When loaded by another player, the Box2D solver attempts to read null memory addresses, instantly throwing an unhandled level exception.
The level editor frequently writes 14-decimal floating point coordinates (e.g. x="142.928174928172"). Truncating these coordinates to 1 decimal place reduces raw text size by 40% to 65% without any visible displacement in level geometry.

Frequently Asked Questions
The level editor automatically exports floating-point numbers with up to 14 decimal places (e.g. 150.2948192847182). By rounding coordinates to 1 decimal place (0.1m precision), the cleaner routinely cuts 40% to 65% of raw XML bytes without any perceptible change to obstacle positioning or collision physics.
The two most frequent causes are orphan joint links (joints referencing non-existent body IDs deleted during editing) and unclosed tags caused by clipboard truncation. This optimizer automatically purges orphan references and repairs missing closing </levelXML> tags.
No. Physical properties like density, friction, restitution, motor speeds, and joint limits are preserved intact. Only redundant coordinates, invalid references, and 0-area invisible shapes are modified or removed.
