java中的多色变化文本
我喜欢五颜六色的文字,我列出了所有的颜色 我有5克的抽绳();函数运行时,每个函数都应该是列表中的下一个颜色(一个在另一个之上) 然后在我的构造函数中:java中的多色变化文本,java,arrays,list,graphics,colors,Java,Arrays,List,Graphics,Colors,我喜欢五颜六色的文字,我列出了所有的颜色 我有5克的抽绳();函数运行时,每个函数都应该是列表中的下一个颜色(一个在另一个之上) 然后在我的构造函数中: colors[0] = new Color(255, 0, 0); colors[1] = new Color(255, 127, 0); colors[2] = new Color(255, 255, 0); colors[3] = new Color(127, 255, 0); colors[4] = new Color(0, 255, 0
colors[0] = new Color(255, 0, 0);
colors[1] = new Color(255, 127, 0);
colors[2] = new Color(255, 255, 0);
colors[3] = new Color(127, 255, 0);
colors[4] = new Color(0, 255, 0);
colors[5] = new Color(0, 255, 127);
colors[6] = new Color(0, 255, 255);
colors[7] = new Color(0, 127, 255);
colors[8] = new Color(0, 0, 255);
colors[9] = new Color(127, 0, 255);
colors[10] = new Color(255, 0, 255);
colors[11] = new Color(255, 0, 127);
我如何使每个字母都有不同的颜色
Set The Color: g.setColor(Color object);
Example: g.setColor(colors[5]);
Write Text: g.drawString(String, x, y);
Example: g.drawString("S", 200, 300);
因此,我希望S是颜色,颜色[0],我在下面做了一个表格:
Starting | First | Second | Fifth
S -- 0 11 10 7
N -- 1 0 11 8
A -- 2 1 0 9
K -- 3 2 1 10
E -- 4 3 2 11
所以它会在每种颜色之间循环:
我试着做一个函数,我删除了代码,因为我是个白痴-_-
在我的主类中,我有一个游戏循环,它调用tick和render方法,tick first然后render
我有一个名为STATE的枚举,其中包含menu和game,然后STATE类型的变量gameState被设置为STATE.menu
public enum state {
Menu,
Game,
}
public state gameState = state.Menu;
当gameState等于STATE.menu时,它将调用menu.render(g)(如果我理解正确,主要有两个问题:
- 在给定数组中循环绘制不同颜色的字母
- 更新颜色(但在固定时间,而不是每个“勾号”)
int colorOffset = ... // Counted up or down all the time
// The index of the color for the i'th letter
int colorIndex = (i+colorOffset)%colors.length;
if (colorIndex < 0) colorIndex += colors.length;
g.setColor(colors[colorIndex]);
到目前为止做得很好。你的问题是什么?这只是你所做工作的列表。你能让你的问题更简洁吗?一个问题中似乎有多个问题。“因为勾号方法每0.0000000000001秒调用一次”-哇,你不喜欢你的用户…@MadProgrammer嘿,现在,1/5百万分之一秒是一个完全合理的更新时间:PI不理解这个问题?我如何才能让它向右,而不是向左?你基本上必须减少
颜色偏移量
…并确保在模运算后索引是正的。(后者是我无论如何都会添加的东西,因为否则,在运行几年之后,偏移量可能会溢出…)。代码已经相应地更新了。Ohhhmagod它看起来棒极了!
the letter a should be colors[0]
and then b, colors[1]
and c, colors[2]
so a would be colors[2]
so b would be colors[0]
so c would be colors[1]
int colorOffset = ... // Counted up or down all the time
// The index of the color for the i'th letter
int colorIndex = (i+colorOffset)%colors.length;
if (colorIndex < 0) colorIndex += colors.length;
g.setColor(colors[colorIndex]);
