Control Flow and Functions

GDScript's syntax leans heavily on Python: indentation defines blocks, no curly braces, no semicolons.

var xp = 45

if xp >= 100:
    print("Level up!")
elif xp >= 50:
    print("Almost there")
else:
    print("Keep going")

Loops

for i in range(5):
    print(i)

var items = ["sword", "shield", "potion"]
for item in items:
    print(item)

var tries = 0
while tries < 3:
    tries += 1

for item in items iterates directly over any array-like value, exactly like Python's for x in list.

Functions

func calculate_damage(base: int, multiplier: float = 1.0) -> int:
    return int(base * multiplier)

var dmg = calculate_damage(10)        # 10, uses the default multiplier
var crit = calculate_damage(10, 2.0)   # 20

multiplier: float = 1.0 gives the parameter a default value, callers can omit it entirely. -> int is an optional return-type annotation, purely for clarity and editor tooling, not enforced as strictly as some statically-typed languages.
