How to Fix RTS Minimap Clicks Mapping to the Wrong World Spot in Unity

If minimap clicks send the camera to the wrong place, your screen-to-world mapping is off. Converting through normalized UV and real world bounds fixes it. Here is how.

How to fix it

1. Get normalized UV in the rect

Use RectTransformUtility.ScreenPointToLocalPointInRectangle to get the click relative to the minimap rect, then divide by the rect size to get a 0-1 UV.

2. Map UV to world bounds

Scale the UV across the playable world's min and max world coordinates (not the texture's pixel size) so the mapping matches the terrain the minimap represents.

3. Account for aspect and rotation

If the minimap is rotated or its aspect differs from the world, apply the inverse rotation and correct aspect before mapping, so corners and edges land where the player expects.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every Unity error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
