我正在尝试为OS X制作一个QR码生成器,但是我还没有继续制作一个更加丰富多彩的QRCode,黑色和白色我正在使用CIQRCodeGenerator进行CIImage过滤器我将如何制作这个我已经在我的应用程序中实现了一个示例代码: -
+ (NSImage *)createQRImageForString:(NSString *)string size:(CGSize)size {
// Setup the QR filter with our string
CIFilter *filter = [CIFilter filterWithName:@"CIQRCodeGenerator"];
[filter setDefaults];
NSData *data = [string dataUsingEncoding:NSUTF8StringEncoding];
[filter setValue:data forKey:@"inputMessage"];
CIImage *image = [filter valueForKey:@"outputImage"];
// Calculate the size of the generated image and the scale for the desired image size
CGRect extent = CGRectIntegral(image.extent);
CGFloat scale = MIN(size.width / CGRectGetWidth(extent), size.height / CGRectGetHeight(extent));
// Since CoreImage nicely interpolates, we need to create a bitmap image that we'll …当我有多个敌人时,他们有一个漂浮的健康号码250.0f.因此,当我向其中一个人射击时,每次向敌人开枪时,这个数字应减少50.但是这是我的问题:第一个敌人死了大约4/5射击它,但当我开始射击另一个(在第一个敌人之后),它需要1次射击并且死亡.
所以这里是玩家Bullet的Bullet脚本,名为Bullet.cs:
public class Bullet : MonoBehaviour {
public GameObject BulletObject;
public GameObject GlobelObjectExplosion;
public GameObject GlobelBulletExplosion;
public float life = 3.0f;
private EnemyAI enemy;
private Transform bulletTransform;
// Use this for initialization
void Start () {
}
void OnTriggerEnter(Collider other)
{
if(other.gameObject.tag == "Enemy")
{
EnemyAI.currEnemyLife -= 50;
Player.score += 50;
//Creates an explosion on collision
GameObject objBullet = Instantiate(GlobelBulletExplosion, transform.position, Quaternion.identity) as GameObject;
Destroy(objBullet, 2.0f);
Debug.Log("ColliderWorking");
if(EnemyAI.currEnemyLife <= 0.0f)
{
Destroy(other.gameObject);
//creates an explosion when enemy …我无法将我的CoreData同步到iCloud I Keep在控制台中输入错误说
