我试图随着时间的推移将平方纹理纹理像素移动到纹理的中心.下面的代码正在做它的工作,除非我希望像素在到达几何体的中心(一个平面)时消失,而现在它只是变得越来越小,而时间增加,纹理看起来像收缩.

uniform float time;
varying vec2 vUv;

void main() {

    vec2 center = vec2(0.5, 0.5);
    vec2 newPosition = vec2(vUv.x + t * (center.x - vUv.x), vUv.y + t * (center.y - vUv.y);

    gl_FragColor = texture2D( texture, vec2(newPosition.x, newPosition.y) );
}

编辑:

把它想象成纹理中心的黑洞.

当我创建一个新的操作银行时，我需要自动将当前日期添加到我的数据库中。我正在使用休眠。谢谢

import java.io.Serializable;
import java.sql.Date;
import javax.persistence.*;
import org.hibernate.annotations.Generated;
import org.hibernate.annotations.GenerationTime;

@Entity
public class OperationBank implements Serializable {
private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;

private String wordring;

private Double amount;

@Generated(GenerationTime.ALWAYS)
@Temporal(javax.persistence.TemporalType.DATE)
private Date dateoperation = new java.sql.Date(new java.util.Date().getTime());

@OneToOne
private Account account;

我想知道如何使用javascript/jQuery获得不透明度参数.

例如:rgba(255,255,255,0.5)

我需要0.5

谢谢

需要一些帮助,请注意以下错误:

TypeError:'unicode'对象不支持项目分配

    print json.dumps(menuDic, indent=5, sort_keys=True)

谢谢

我想String用11ID 生成带有数字的数字.
例如:有一个帐户ID=12会给00000000012

之后我需要从字符串中检索此id.

例如:用绳子00000000022给出ID=22
