我正在用 kineticjs 开发一个棋盘游戏,其中一个图片以两种方式同时动画:
1 - 使用补间动画 x 和 y 坐标,从位置 a 到 b。我这样做没有问题,从用户那里获得输入。
2 - 在 sprite 中,我们应该看到被抬起的部分(第 0 > 4 帧),并在上一个动画中保持向上,最后,它从 4 动画到 8,然后返回到初始空闲状态
到目前为止,我有这个:
var animations = {
idle: [{x: 0, y: 0, width: 100, height: 100}],
up: [{x: 0, y: 0, width: 100, height: 100},
{x: 100, y: 0, width: 100, height: 100},
{x: 200, y: 0, width: 100, height: 100},
{x: 300, y: 0, width: 100, height: 100}],
down: [{x: 400, y: 0, width: 100, height: 100},
{x: 500, y: 0, width: 100, height: 100},
{x: 600, y: 0, width: 100, height: 100},
{x: 700, y: 0, width: 100, height: 100}]
};
/* coordinates_js is an array of the possible x and y coordinates for the player. like this, the player is created in the first coordinate, the starting point
*/
var player = new Kinetic.Sprite({
x: coordinates_js[0].x,
y: coordinates_js[0].y,
image: imageObj,
animation: 'idle',
animations: animations,
frameRate: 7,
index: 0,
scale: 0.4,
id: "player"
});
imageObj.onload = function() {
var targetx = null;
var targety = null;
var targetIndex = null;
var playerIndex = 0;
document.getElementById('enviar').addEventListener('click', function() {
targetIndex = document.getElementById("targetIndex").value;
var destino = coordinates_js[targetIndex];
var tween = new Kinetic.Tween({
node: player,
x: destino.x,
y: destino.y,
rotation: 0,
duration: 5
}).play();
console.log("x: " + destino.x + "y: " + destino.y)
playerIndex = targetIndex;
tween.play();
player.setAnimation("up");
player.afterFrame(3, function(){
console.log("idle")
player.setAnimation("idle");
})
}, false);
playLayer.add(player);
stage.add(playLayer);
player.start();
}
这里的问题是精灵动画从 1 播放到 4 并进入空闲状态;我需要它一直保持到补间结束。我本可以有:
player.setAnimation("up");
player.afterFrame(3, function(){
console.log("idle")
player.setAnimation("idle");
})
这抬起了这块,但不会让它掉下来。那么,我该怎么做呢?
非常感谢你们
