ASCII Fire

is an interactive ASCII animation that simulates flickering flames using nothing but characters. Watch heat rise, tongues of fire dance and curl, and glowing embers drift through the air as the fire breathes in rhythmic pulses.

Instruction

Fire Modes

Mode	Description
Wall of Fire	Full-width fire spanning the entire bottom. Classic inferno look.
Campfire	Centered fire source (30% width). Cozy, focused flames.
Torches	3–4 evenly spaced torch flames. Medieval atmosphere.
Candles	5–8 small, delicate flames. Calm, intimate lighting.

Controls

Control	Description
Intensity	Heat level of the fuel source. Higher values create taller, brighter flames.
Wind	Horizontal force pushing the flames. Negative values blow left, positive blow right.
Decay	How quickly flames cool as they rise. Lower values create taller flames.
Turbulence	Random flickering intensity. Higher values create more chaotic, dancing flames.
Thickness	Number of fuel rows at the bottom. More rows create a wider, more stable fire base.

Effects

Effect	Description
Embers	Slow-floating particles that drift upward from the flames.
Sparks	Quick, bright particles that shoot up and fade rapidly.
Pulse	Rhythmic breathing effect that modulates the fire intensity.

Visual Options

Palette: Color scheme for the flames (Classic, Blue, Lava, Matrix, or Mono)
Charset: ASCII characters used to render the fire
FPS: Animation speed (frames per second)
