What is Fresh Cooked Tweens?
It’s a lightweight tweening library! It’s fast and performant, and crafted around a real workflow to be very easy to use and adaptable. I have also cooked up some tasty docs for you, take a look at the readme on the repo’s front page.
Why Tweens?
Tweens are great for those little polish animations in any project - they see a huge amount of use in UI, even in large budget endeavors. So many things just need a little ease, instead of a harsh linear movement. For example:
- A coin bobbing in the air
- a pause menu moving onscreen
- transitioning between camera locations
- a purchased item moving into your bag
- a collected item moving into a HUD counter
I’ll get an even broader use out of them for my personal projects, like those bobbing animations players love so much:
Or even main character animations for the right kind of project:
WaddleRotator = GetMesh()->GetRelativeRotation();
WaddleTween = FCTween::Play(
-WADDLE_ANGLE, WADDLE_ANGLE,
[&](float t)
{
WaddleRotator.Pitch = t;
GetMesh()->SetRelativeRotation(WaddleRotator);
},
WADDLE_SECS, EFCEase::InOutSine)
->SetYoyo(true)
->SetLoops(-1);
Why not just use Timelines?
Timelines work great for some purposes, but tweens are generally easier to set up, easier to tweak, and you just get stuff done faster, which results in higher quality stuff that you have put more iterations into. Fresh Cooked Tweens gives you a much easier way to set up those animations in code, as well.
