Standard library

aego/math — Pi Tau; Floor Ceil Round Trunc Sqrt Sin Cos Tan Asin Acos Exp Log Abs Sign Min Max Clamp Lerp Atan2 Pow Deg2Rad Rad2Deg; AbsInt MinInt MaxInt ClampInt; Vec2: Length Normalize Dot Cross Dist Rotate Angle LerpVec2; Vec3: Length3 Normalize3 Dot3 Cross3 Dist3 LerpVec3; Quat: QuatEuler QuatAxisAngle QuatMul QuatRotate QuatSlerp QuatLookDir. There is no overloading: Vec3 variants carry a 3 suffix, int variants an Int suffix.

aego/log — Debug Info Warn Error(msg string). Build messages with + and string(x).

aego/rand — Float() float in [0,1), Bool() bool, Int(min, max int) int in [min, max), Range(min, max float) float, Seed() int. The source is the world's seeded generator; a replay with the same seed reproduces the numbers.

aego/time — Delta() float, Fixed() float, Elapsed() float, Frame() int.

aego/input — Down(k) Pressed(k) Released(k) bool, MouseDown(b) MousePressed(b) bool, MousePos() Vec2, Axis(name string) float. Keys are input.Key.Space or the constants input.KeySpace, digits input.KeyDigit1; buttons input.MouseLeft. Axes are declared in project.aego:

input {
  axes {
    horizontal { negative=A positive=D altNegative=Left altPositive=Right }
    vertical   { negative=S positive=W altNegative=Down altPositive=Up }
  }
}

aego/scene — Find(path string) NodeRef from the scene root, Instantiate(prefab AssetRef<Prefab>, parent NodeRef) NodeRef, Destroy(NodeRef). New nodes appear at the end of the phase; their scripts receive Ready before the next Update.

aego/testing — available only under aego test: True(cond bool, msg string), False(…), Equal(got, want int), EqualFloat(got, want, eps float), EqualString(got, want string), Fail(msg string). A failed assertion stops the test and reports the file and line.

Engine modules add their own host modules (aego/physics, aego/audio, …); each is documented in its module's reference and in the generated library stubs.
