Question

如何确保在玩家移动并播放动作动画后，机架（空闲）的动画开始，这应该在两个方向（右，左）都有效

Answer 1

我找到了解决方案，必须使用keyboard_check_released

var right_move = (keyboard_check(ord("D")));
var left_move = (keyboard_check(ord("A")));
var right_move_release = (keyboard_check_released(ord("D")));
var left_move_release = (keyboard_check_released(ord("A")));


if (right_move) {
    phy_position_x += 10;
    sprite_index = Move_right;
    image_speed = 1;
}

if (right_move_release) {
    sprite_index = Idle_right;
}


if (left_move) {
    phy_position_x -= 10;
    sprite_index = Move_left;
    image_speed = 1;
}

if (left_move_release) {
    sprite_index = Idle_left;
}

Answer 2

我认为，或者，您也可以使用elseif 语句来代替，这样可以使代码更清晰：

var right_move = (keyboard_check(ord("D")));
var left_move = (keyboard_check(ord("A")));

if (right_move) {
    phy_position_x += 10;
    sprite_index = Move_right;
    image_speed = 1;
} else {
    sprite_index = Idle_right;
}


if (left_move) {
    phy_position_x -= 10;
    sprite_index = Move_left;
    image_speed = 1;
} else {
    sprite_index = Idle_left;
}

如果左侧精灵与右侧精灵相同，那么您还可以使用image_xscale并将缩放比例更改为1或-1翻转精灵。
