In the game, players perform a certain operation, often need to give the player a hint to tell the player operating result: success or failure prompts. Embodiment may be used to prompt the elastic block, the text may be fading. Display some information block is elastic, and with the OK / Cancel buttons. Fade text is display text on and gradually drift hidden, until it disappears. This process usually only takes about 1 second.
Today to share with you realize the writing prompt.
Implement (1) First create a new text, the text is used to control the animation:
The main idea:
the definition of a public variable color and text, easy to modify in the editor;
text of the statement component assigned text, color, position initialization;
declare a float variable for controlling character animation time.
Update on time - the judge <0? End text animation: reduce transparency, move up

public class FlyText : MonoBehaviour
{
public Color color;//文字的颜色
public string content;//文本内容
Text t;//Text组件
void Start()
{
t = transform.GetComponent<Text>();
t.text = content;//设置组件
t.color = color;
t.rectTransform.anchoredPosition = new Vector2(t.rectTransform.anchoredPosition.x, t.rectTransform.anchoredPosition.y + 30);
}
float fadeTimer = 1;
void Update()
{
fadeTimer -= Time.deltaTime;
t.color = new Color(color.r, color.g, color.b, fadeTimer);
t.rectTransform.anchoredPosition = new Vector2(t.rectTransform.anchoredPosition.x, t.rectTransform.anchoredPosition.y + (1 - fadeTimer));
if (fadeTimer < 0)
{
GameObject.Destroy(this.gameObject);
}
}
}
(2) create a game object, to add Text component, set according to demand, the addition of the FlyText script. Prefabs saved in the Resources folder / Text_FlyText.
(3) the use of prefabricated:
adding text prompt needs a script flyText method for instantiating preform, and converted to the GameObject, set the parent object, acquires the FlyText script component, the content of the text and assign colors.

void flyText(Vector3 pos,Color color,string content)
{
GameObject go = Instantiate(Resources.Load<GameObject>("Prefabs/Text_FlyText"), pos, Quaternion.identity) as GameObject;
go.transform.SetParent(GameObject.Find("Canvas").transform);
FlyText ft = go.GetComponent<FlyText>();
ft.color = color;
ft.content = content;
}
(4) call flyText method:
flyText(new Vector3(0, 0, 0), new Color(1, 0, 0, 1), "文字提示内容");
For example: I need to start the game interface, click the Start button when the prompt text "into the game"
