ktx v1.9.8-b2 Release Notes

Release Date: 2018-03-07 // about 6 years ago

  • Contains notable breaking changes to ktx-math operators in order to prevent calculation errors arising from vectors and matrices mutability.

    • ⚡️ [UPDATE] Updated to Kotlin 1.2.30.
    • ⚡️ [UPDATE] Updated to Kotlin Coroutines 0.22.5.
    • ⚡️ [UPDATE] Updated to Dokka 0.9.16.
    • ⚡️ [UPDATE] Updated to Gradle 4.6.
    • [FEATURE] (ktx-math) dot and x infix functions added to Vector2 and Vector3 allow to calculate dot products and cross products of two vectors respectively.
    • [FEATURE] (ktx-box2d) Initiation blocks of Body in World.body extension method is now optional thanks to default lambda parameters in inlined functions.
    • [FEATURE] (ktx-box2d) World.query extension method allowing to execute AABB query with idiomatic Kotlin.
    • [CHANGE] (ktx-math) Binary operators of Vector2, Vector3, Matrix3 and Matrix4 (+, -, *, /) no longer modify the first vector or matrix. Instead, they create new instances of vectors or matrices that store the operation result. Use the assign operators (+=, -=, *=, /=) instead to avoid creating new instances.
    • [CHANGE] (ktx-math) New mutating assign operators (+=, -=, *=, /=) were added to Vector2, Vector3, Matrix3 and Matrix4.
    • [CHANGE] (ktx-math) Parameters of matrix vector multiplication operators are switched. vector * matrix does not exist anymore and now is available as matrix * vector.
    • [CHANGE] (ktx-math) Operators of Matrix3 to left-multiply a Vector3 were removed.
