Combat Precision Fix and Health UI Enhancement - #141
Conversation
- Refactored Enemy, Stall, and Projectile models to use Float for health and damage. - Updated MainViewModel and StallUpgradeManager to maintain float precision in combat calculations. - Improved rendering z-sorting in GameBoard.kt to keep overhead effects above ground entities. - Added percentage health text display to enemy health bars. - Updated unit tests and documentation (AGENTS.md, fixes.md).

Excellent points. I've removed the redundant |
- Refactored combat stats to Float to resolve rounding bugs. - Implemented percentage health display for enemies. - Optimized rendering z-sorting to keep projectiles/VFX above world entities. - Cleaned up redundant casts and unified death thresholds in game engine. - Added safety guards for potential division by zero in UI. - Updated documentation and test suite.

In MainViewModel.kt (around the combat loop), lines like enemy.health.toFloat() and proj.damage.toFloat() are now no-ops. |
Acknowledged. I have removed the redundant |
- Removed redundant .toFloat() calls on health and damage. - Aligned hit-loop early exit with the < 1.0f death threshold to prevent kill double-counting. - Verified all tests pass. Co-authored-by: candour <4670475+candour@users.noreply.github.com>

This PR addresses a core combat logic bug where precision loss occurred during health and damage calculations due to the use of integers. By refactoring these fields to
Float, we ensure that damage modifiers and armor buffs are applied accurately.Additionally, this PR includes:
