我遇到的问题是，在对角线移动过程中游戏精灵动画无法播放，它只会卡在对角线动画的第一帧上。如果有人知道什么事，我会非常感激。

答案 0 :(得分：0)
您的精灵动画永远不会有机会在对角线上运行，因为您在每个刻度线上调用detectKeys()，如果对角线组合评估为真，则会启动动画结束。您可以在常规步行动画中找到正确的想法，首先检查您的播放器是否已经在gotoAndPlay之前行走，如下所示：
if (keysPressed[38] === 1) {
if (player.currentAnimation !== "walkUp") { player.gotoAndPlay("walkUp"); }
moveChar(player, 0, -1);
}
您也需要为对角线执行此操作。类似的东西：
if (keysPressed[38] === 1 && keysPressed[37] === 1) {
if(player.currentAnimation !== "walkDiagUpLeft") { player.gotoAndPlay("walkDiagUpLeft"); }
}
