Small tool for sprite PolygonCollider2D optimization (got tired of manually adjusting sprite collider vertices when doing this small ‘game’<\/a> for android)

\n

Documentation:<\/strong>
\nPolygonCollider2D_Optimizer_web.pdf<\/a><\/p>\n

Features:<\/strong>
\n– Super simple workflow, real results! (increased frame rate, no more “floating colliders”)
\n– Optimize, Scale, Move, Filter\/Remove PolygonCollider2D vertices & paths (for every selected sprite)
\n– Remove inner paths, Keep only largest path, Remove paths based on vertex count
\n– Add, Reset, Remove PolygonCollider2D’s (for every selected sprite)
\n– 4 Scaling modes: Estimate Neighbours, Standard Scaling, Normalized Scaling, Normalized Scaling (local center). *Scaling is useful for avoiding Box2D skin margin problems<\/a><\/p>\n

Limitations:<\/strong>
\n– This uses unity generated PolygonCollider2D’s, its not reading the image data at all, those generated polygoncolliders are then optimized
\n– Not all actions are undoable (see docs), but you can always reset collider to unity<\/p>\n

Roadmap\/Future ideas:<\/strong>
\n– feel free to suggest!<\/p>\n

Basic Tutorials
\n“Remove Inner Paths & Optimize”
\n<\/strong>-Start optimizer from Window \/ PolygonCollider2D Optimizer
\n– Select some sprite with PolygonCollider2D from scene\u00a0 (you should see in the optimizer window how many paths & vertices the collider has)
\n– Click “Remove inner paths” few times (until all inner paths are removed) \/ alternatively you could click “Keep biggest path only”
\n– Set Filter angle to 18 or so (seems good value in most cases)
\n– Click Optimize (you can click Optimize again, just incase some edge went below this angle on first round)
\n– And you are done!<\/p>\n

non-optimized scene<\/strong>: (starts to slowdown after 350+ sprites with default polygon colliders)

Optimized scene<\/strong>: (still running nicely at 600 optimized sprites, starts to dip below 40-50 at ~700 sprites)
\n* (optimizing workflow: select all objects, click Optimize couple times, click Remove inner paths 3-4 times, click scale twice – Done!)
