Question

基本上我正在创建这个游戏，并且有一个节点（球）以设定的速度绕过一条路径。设置速度在GameProcessSettings.h文件中定义，代码如下，

#define SPEED_MOVE_PLAYER_MIN 28
#define SPEED_MOVE_PLAYER_MAX 9000

现在在控制节点速度的文件中，这是代码。

- (void)moveTo:(NSString *)moveDirection currentPlayerPosition:(NSString *)playerPosition {
    [self removeAllActions];

    speed-= IncreaseSpeedValue;
    if (speed < SPEED_MOVE_PLAYER_MIN) speed = SPEED_MOVE_PLAYER_MIN;
    else {
        [timer invalidate];
        timer = nil;
    }

    SKAction *move;
    if ([moveDirection isEqualToString:@"up"]) move = [SKAction moveToY:self.position.y + PLAYER_MOVE_BY_POINTS duration:speed];
    else if ([moveDirection isEqualToString:@"down"]) move = [SKAction moveToY:self.position.y - PLAYER_MOVE_BY_POINTS duration:speed];
    else if ([moveDirection isEqualToString:@"left"]) move = [SKAction moveToX:self.position.x - PLAYER_MOVE_BY_POINTS duration:speed];
    else move = [SKAction moveToX:self.position.x + PLAYER_MOVE_BY_POINTS duration:speed];

    timer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(increaseSpeed) userInfo:nil repeats:YES];
    IncreaseSpeedValue = -200;

    [self runAction:move];

    _currentMoveDirection = moveDirection;
    _currentPlayerPosition = playerPosition;
}

@end

我如何以及如何使节点每秒移动得更快？

随着时间的推移，提高节点的速度
