unity3d和下OrtHello的使用教程 （二） 移动物体，碰撞等
回顾一下上一次的教程orz，也许有许多地方没有说清楚的，我补充一下
首先是OT的预设物体有：
是不是看到了熟悉的Sprite等物体，首先OT这个物体是一定要一开始就拖到场景中了，它作为一个管理全局的OT物体而存在。
然后是Sprites，Sprites简单来说只有3种：不会自己主动动画的Sprite，会自己主动动画的AnimatingSprite，能填充一定区域范围的FilledSprite，这三种Sprite是直接放进场景中的，
Sprites目录下的Animation是根据SpriteAtlas或者是SpriteSheet的Texture来生成序列帧动画的，主要是设置从第几帧到第几帧是什么动画，这样子方便AnimatingSprite的调用，这些Animation就是放到场景中的OT下的Animation目录中的
Sprites目录下的SpriteAtlas和SpriteSheet都是用来管理Texture的，以后说。
话说，unity有一点我超不喜欢的就是：一个在场景中的物体带有collior 可我不知道是自己附上去的还是通过代码添加的orz
下面是附C#代码
public class CExample2 : MonoBehaviour {
/// ();
// Set block's position
b.position = new Vector2(s + 50 + (x * 85)- (Screen.width/2), 20 - (Screen.height/2));
// Set block's name
b.name = "bottom" + x;
// Link to parent
b.transform.parent = blocks.transform;
}
// Create top horizontal blocks
for (int x = 0; x < c; x++)
{
// Create a new block
OTSprite b = (Instantiate(blockPrototype.gameObject) as GameObject).GetComponent();
// Set block's position
b.position = new Vector2(s + 50 + (x * 85) - (Screen.width / 2), Screen.height - 20 - (Screen.height / 2));
// Set block's name
b.name = "top" + x;
// Link to parent
b.transform.parent = blocks.transform;
}
// Calculate the vertical number of blocks for the current resolution
c = (Screen.height - 50) / 85;
// Calculate vertical center spacing
s = (Screen.height - (c * 85)) / 2;
// Create left vertical blocks
for (int x = 0; x < c; x++)
{
// Create a new block
OTSprite b = (Instantiate(blockPrototype.gameObject) as GameObject).GetComponent();
// Rotate this block 90 degrees
b.rotation = 90;
// Set block's position
b.position = new Vector2(20 - (Screen.width / 2), (Screen.height/2) - 40 - s - (x*85) );
// Set block's name
b.name = "left" + x;
// Link block to parent
b.transform.parent = blocks.transform;
}
// Create right vertical blocks
for (int x = 0; x < c; x++)
{
// Create new block
OTSprite b = (Instantiate(blockPrototype.gameObject) as GameObject).GetComponent();
// Rotate block 90 degrees
b.rotation = 90;
// Set block's position
b.position = new Vector2((Screen.width / 2)-20, (Screen.height / 2) - 40 - s - (x * 85));
// Set block's name
b.name = "right" + x;
// Link block to parent
b.transform.parent = blocks.transform;
}
}
// Find the empty that will act as the stars container
GameObject stars = GameObject.Find("Stars");
if (stars != null)
{
// We will create 50 stars
int c = 50;
for (int x = 0; x < c; x++)
{
// Create a new star
OTSprite s = (Instantiate(starPrototype.gameObject) as GameObject).GetComponent();
// Set star's random position
s.position =
new Vector2(
-1 * (Screen.width / 2) + 50 + Random.value * (Screen.width - 100),
(Screen.height / 2) - 40 - Random.value * (Screen.height - 80));
// Set star's name
s.name = "star" + x;
s.depth = 100 + x;
// Link star to parent
s.transform.parent = stars.transform;
}
}
}
// Application initialization
void Initialize()
{
// Create all objects for this demo
CreateObjects();
// Set initialization notifier - we only need to initialize once.
initialized = true;
}
// Update is called once per frame
void Update () {
// Only go one when Orthello is initialized
if (!OT.isValid) return;
// Call initialization once from this Update() so we can be sure all
// Orthello objects have been started
if (!initialized)
Initialize();
}
} 下面是运动的物体，简称star
public class CStar2 : MonoBehaviour {
OTSprite sprite; // This star's sprite class
Vector2 speed = // Star movement speed / second
new Vector2(150, 150);
float rotation = 90; // Star rotation speed / second
Color startColor =
new Color(0.5f, 1f, 0.5f); // Star's tint color
Color stayColor =
new Color(1f, 1f, 1f); // Star's tint color when overlapping
// Use this for initialization
void Start () {
// get this star's sprite class
sprite = GetComponent();
// Set this sprite's stay/exit/collision delegates
// HINT : We could use sprite.InitCallBacks(this) as well.
// but because delegates are the C# way we will use this technique
sprite.onStay = OnStay;
sprite.onExit = OnExit;
sprite.onCollision = OnCollision;
// Create a random speed for this star
speed = new Vector2(150 + 150 * Random.value, 150 + 150 * Random.value);
// Set star's color
sprite.tintColor = startColor;
// register the start material so we can use it later for assignment
OT.RegisterMaterial("Star-start", new Material(sprite.material));
var m = new Material(sprite.material);
// register the material so we can use it later for assignment
m.SetColor("_EmisColor", stayColor);
OT.RegisterMaterial("Star-stay", m);
}
// Update is called once per frame
void Update () {
// adjust this star's position
sprite.position += speed * Time.deltaTime;
// adjust this star's rotation
sprite.rotation += (rotation * Time.deltaTime);
}
// OnStay delegate is called when star enters (overlaps) another 'collidable' object
// !IMPORTANT - This sprite's collidable setting has to be true otherwide
// collision delegates will not be called
/// 下面是边界
public class CBlock2 : MonoBehaviour {
OTSprite sprite; // This block's sprite class
bool colorFade = false; // color fade notifier
float fadeTime = 0; // fade time counter
float fadeSpeed = 0.25f; // fade speed
Color startColor =
new Color(0.3f, 0.3f, 0.3f); // block color
// Use this for initialization
void Start () {
// Lookup this block's sprite
sprite = GetComponent();
// Set this sprite's collision delegate
// HINT : We could use sprite.InitCallBacks(this) as well.
// but because delegates are the C# way we will use this technique
sprite.onCollision = OnCollision;
// Set this block's tinting to the start color
sprite.tintColor = startColor;
// Register this material with Orthello so we can re-use it later
OT.RegisterMaterial("Block-start", new Material(sprite.material));
// Generate Highlight materials and store them
for (int i=0; i<10; i++)
{
var m = new Material(sprite.material);
m.SetColor("_EmisColor", Color.Lerp(Color.white,startColor,0.1f * i));
OT.RegisterMaterial("Block-tint"+i, m);
}
}
// Update is called once per frame
void Update()
{
if (colorFade)
{
// We are color fading so set block's color to fade time dependend color
int fadeIndex = (int)(Mathf.Floor((fadeTime / fadeSpeed) * 10));
sprite.material = OT.LookupMaterial("Block-tint" + fadeIndex);
// Incement fade time
fadeTime += Time.deltaTime;
if (fadeTime >= fadeSpeed)
{
// We have faded long enough
colorFade = false;
if (OT.LookupMaterial("Block-start") == null)
print("Block-start material not found!");
// Set block's color to start color
sprite.material = OT.LookupMaterial("Block-start");
}
}
}
// This method will be called when this block is hit.
