rsanim

A basic state machine for managing sprite animations.

Example usage:

```rust use rsanim::*; use std::collections::HashMap;

[derive(Clone, Eq, PartialEq, Hash, Debug)]

enum Animation { Idle, Run, }

[derive(Clone, Debug, PartialEq)]

struct Params { pub speed: f32, }

let mut statemachine = StateMachine::new( Animation::Idle, HashMap::from([ ( Animation::Idle, State { duration: 0.5, repeat: true, }, ), ( Animation::Run, State { duration: 1.0, repeat: true, }, ), ]), vec![ Transition { startstate: TransitionStartState::Node(Animation::Idle), endstate: TransitionEndState::Node(Animation::Run), trigger: Trigger::Condition(Box::new(|x: &Params| x.speed > 0.0)), }, Transition { startstate: TransitionStartState::Node(Animation::Run), end_state: TransitionEndState::Node(Animation::Idle), trigger: Trigger::Condition(Box::new(|x: &Params| x.speed <= 0.0)), }, ], Params { speed: 0.0 }, ) .unwrap(); ```

Update the state machine as time passes:

rust state_machine.update(delta_time);

Update the parameters that are used to determine conditional transitions:

rust state_machine.update_parameters(&|x| { x.speed = 1.0; });
