The Super Mario Bros. Game is progressing.
I’ve added some new animations to Mario, walking, jumping, standing still (idle), and dying.
/// Options list each animation.
enum MarioAnimationState {
idle,
walk,
jump,
die,
}
class Mario extends SpriteAnimationGroupComponent<MarioAnimationState>
...
// Mario's onload method,
@override
Future<void> onLoad() async {
await super.onLoad();
final SpriteAnimation idle = await AnimationConfigs.mario.idle();
final SpriteAnimation walking = await AnimationConfigs.mario.walking();
final SpriteAnimation jumping = await AnimationConfigs.mario.jumping();
final SpriteAnimation die = await AnimationConfigs.mario.die();
// Possible animations provided by SpriteAnimationGroupComponent.
animations = {
MarioAnimationState.idle: idle,
MarioAnimationState.walk: walking,
MarioAnimationState.jump: jumping,
MarioAnimationState.die: die,
};
// The current animation.
current = MarioAnimationState.idle;
}
Mario is able to move based on user keyboard input.
/// Update Mario's position via keyboard press.
void marioAnimationUpdate() {
// If he's not on the ground, he's in the air.
if (!isOnGround) {
current = MarioAnimationState.jump;
}
// If the left/right keys are pressed, he's walking.
else if (_hAxisInput < 0 || _hAxisInput > 0) {
current = MarioAnimationState.walk;
}
// Otherwise, he's idle.
else if (_hAxisInput == 0) {
current = MarioAnimationState.idle;
}
}
/// Perform vertical jump.
void jump() {
// Mario has a negative velocity when going up
// vetically on the y-axis.
velocity.y = -_jumpSpeed;
isOnGround = false;
// Play jump sound based on power type.
switch(_powerType){
case PowerType.small:
FlameAudio.play(Globals.jumpSmallSFX);
break;
case PowerType.big:
case PowerType.fire:
FlameAudio.play(Globals.jumpSuperSFX);
break;
}
}
The die effect takes place when he has a collision with invisible empty blocks at the bottoms of the pits on the map.
@override
void die() {
isDead = true;
// Start timer for how long mario is moving upwards
// before reversing downwards.
_dieUpwards.start();
current = MovementState.dead;
// Play sound bite for Mario losing.
FlameAudio.play(Globals.mariodieSFX);
// Set global variable used for HUD info.
gameRef.hudData.gameOver.value = true;
super.die();
}
