SA:DynamicHUD V2.01

SA:DynamicHUD V2.0
A physics-driven, fully reactive HUD for GTA San Andreas
SA:DynamicHUD is not just a reskin — it is a completely scripted interface that reacts to everything happening around you in real time. Every element on screen is alive. The HUD sways when you drive, shakes when you take damage, pulses when you are dying, and syncs its colors to your wanted level. Built entirely in Lua with 17 independent systems working together as one.
MOTION SYSTEM
The entire HUD drifts and tilts based on your vehicle speed and driving direction using real sine and cosine rotation math. The faster you go, the more the screen leans into the movement. On foot the HUD stays stable. Swimming adds a gentle wave motion. All movement uses double-layer smoothing so every transition feels natural and never snappy.
IMPACT & DANGER
Taking damage triggers an instant screen shake. The intensity scales with how much HP or armour you lost and fades out naturally using physics decay. Below 25 HP a heartbeat sway activates — the lower your health the stronger it pulses. A vignette overlay appears at the edges of the screen: red when HP is critical, blue when oxygen is low underwater, and purple when both are active simultaneously. The pulse speed increases the closer you are to death.
WANTED LEVEL & RADAR
The moment your wanted level changes, the stars animate in with a smooth arc pop effect and fade in from zero. The star color cycles between red and blue in a police siren pattern. The radar map and borders react with the exact same color wave at the same frequency — so the stars, the map, and the borders all shift together as one unified effect.
COMBAT & WEAPONS
Every weapon has its own unique angle and muzzle flash position. Swapping weapons plays a pop animation with professional easing and a fade-in. Recoil behaves differently depending on weapon type — pistols kick sharply, automatics climb gradually, the minigun has a controlled climb to prevent drifting. The muzzle flash on the minigun cycles through 6 animation frames.
The ammo counter color shifts from white to orange to red as ammunition runs low. An empty clip triggers a red shake effect. Weapons with infinite ammo display a smooth RGB color cycle. The crosshair texture switches automatically per weapon class and turns red when locking onto an enemy.
MONEY & POWER
The money counter scrolls smoothly to its new value instead of jumping. Earning money flashes yellow, losing money shakes and flashes red. The power bar uses a 5-state color system that goes from a critical red strobe at the bottom to a golden celebration pulse when reaching full power.
TECHNICAL HIGHLIGHTS
Fully frame-rate independent — all motion uses a unified delta correction
Zero memory leaks — images and charts created once at startup, never per frame
All HUD elements share the same swayed anchor point and move together including wanted stars
Weapon configs and crosshair textures use lookup tables for clean and efficient code
Fixed fake armour and breath bar display logic from common Lua HUD bugs
