Ever wanted to animate text smoothly? Or maybe just scale a text up by some non-integer value? With vectors you can!

Turn down the volume for optimal experience! (unless you're running this within PICO-8, in which case it should sound all chill)

Big thanks to pancelor for squeezing this down from 323 to 251 characters, and for teaching me some wizard-level golfing tricks!

Newtonian gravity simulation

It's a bit unstable. Vector math and fixed point numbers don't mix too well, although I'm sure this could be modified to better utilize the available digit range..

Press Z to pause and adjust the velocities.
Press Ctrl+R to reset the simulation.

Animation/tweening library [WIP]

Sun, 21 Feb 2021 18:35:05 UTC

I'm working on this small animation library. It adds a straightforward way to animate an object's state.

Usage example:

Let's say there's a game object called "progress", representing a progress bar we want to animate:

progress={value=0}

we could animate the value rising from 0 to 100 by adding this to something that triggers the progress to start:

tween(progress,{value=100})

and in _update() we want to call the animate() function to keep updating the value, until it's duration has elapsed:

if has_animations(progress) then animate(progress) end

Demo

Configuration

There are some global variables you can override:

animate_default_duration=0.4
animate_default_easing=ease_quad_out
animate_key="__a" --which key should contain the tweening animation state

You can also add your own easing functions:

function my_easing(t)
 return t*t*t
end
add(animate_easings,my_easing)
ease_my_easing=#animate_easings

Arguments

tween(node,target,options)

node - table that contains the value that should be animated
target - table of the values that should be tweened
[options.duration] - how long the tween should play
[options.easing] - easing function (included easings: linear, quad_in, quad_out and quad_in_out)
[options.custom_time] - custom starting time

Tweens are removed automatically once the animation completes. Starting a new animation for a key with an active animation will overwrite the previous one, continuing animating from it's current value.

Download

The most recent version is available at https://github.com/thykka/pico-8-libs/blob/main/animate.lua

Changelog

v3
- refactored & parametrized almost everything
- animate_key() replaced by tween()
- can now tween multiple values with one tween() call

Screen fill benchmark

Checking out a couple of different methods to fill the screen.

cls seem slightly faster than memset. I wonder if the difference is due to the multiplication op, or if there's something else going on...
