📽 Deetween
A cool animation library for the D programming language. Deetween is a single-file library designed to be a simple foundation for creating complex animation systems.
Types
- EasingFunc
- TweenMode
- Tween
- ValueSequence
- Keyframe
- KeyframeGroup
Examples
Tween
A simple a-to-b animation that lasts 1.0 seconds.
import deetween;
void main() {
enum a = 9.0;
enum b = 20.0;
enum totalDuration = 1.0;
enum dt = 0.001;
auto tween = Tween(a, b, totalDuration, TweenMode.bomb);
assert(tween.now == a);
while (!tween.hasFinished) {
float value = tween.update(dt);
assert(value >= a && value <= b);
}
assert(tween.now == b);
}
ValueSequence
A simple a-to-b animation where each value lasts 0.1 seconds.
import deetween;
void main() {
enum a = 9;
enum b = 20;
enum valueDuration = 0.1;
enum dt = 0.001;
auto sequence = ValueSequence(a, b, valueDuration, TweenMode.bomb);
assert(sequence.now == a);
while (!sequence.hasFinished) {
int value = sequence.update(dt);
assert(value >= a && value <= b);
}
assert(sequence.now == b);
}
KeyframeGroup
A simple a-to-b animation that lasts 1.0 seconds.
import deetween;
void main() {
enum a = 9.0;
enum b = 20.0;
enum totalDuration = 1.0;
enum dt = 0.001;
auto group = KeyframeGroup(totalDuration, TweenMode.bomb);
group.append(Keyframe(a, 0.0));
group.append(Keyframe(b, totalDuration));
assert(group.length == 2);
assert(group.now == a);
while (!group.hasFinished) {
float value = group.update(dt);
assert(value >= a && value <= b);
}
assert(group.now == b);
group.clear();
assert(group.length == 0);
}
