DrawHealthBar()

void Terraria.Main.DrawHealthBar ( float X, float Y, int Health, int MaxHealth, float alpha, float scale = 1f, bool noFlip = false )

inline

Draws a small health bar.
F:Terraria.Main.spriteBatch should already be started before calling this method.

Parameters

X	The x-coordinate of the health bar in world coordinates.
Y	The y-coordinate of the health bar in world coordinates.
Health	The current health displayed. The health bar is drawn Health / MaxHealth percent full. If Health <= 0, no health bar is drawn. If Health > MaxHealth , the health bar will not exceed max capacity.
MaxHealth	The maximum health displayed. The health bar is drawn Health / MaxHealth percent full.
alpha	The opacity of the healthbar, where 0f is transparent and 1f is opaque.
scale	The visual scale of the health bar.
noFlip	If true, then the health bar will not adjust its y-position for players with reversed gravity.
