I added very basic animations for Belts, Arms and LongArms.
I split the arms into a base and top image where the top and Item are being rotated depending on the Arm’s cooldown.
fn arm_node(x: &Arm) -> Node {
let mut rotation = PI * x.cooldown() as f64 / Arm::cooldown_max() as f64;
if x.content().is_some() {
rotation = PI - rotation;
}
rotation += PI;
...For Belts I created a few frames with moving direction arrows which I choose depending on cooldown and I also animated the Items to move depending on the cooldown.
fn belt_node(x: &Belt) -> Node {
let cooldown_rel = x.cooldown() as f64 / Belt::cooldown_max() as f64;
let texture = if cooldown_rel < 0.25 {
Texture::Belt1
} else if cooldown_rel < 0.5 {
Texture::Belt2
} else if cooldown_rel < 0.75 {
Texture::Belt3
} else {
Texture::Belt4
};
let input_offset = -0.4 + 0.8 * (1.0 - x.cooldown() as f64 / Belt::cooldown_max() as f64);
