方法

clampf

限定浮点数的最大最小值。
数值大于 max_inclusive 则返回 max_inclusive。
数值小于 min_inclusive 则返回 min_inclusive。
否则返回自身。

参数列表

• value Number
• min_inclusive Number
• max_inclusive Number

示例

var v1 = cc.misc.clampf(20, 0, 20); // 20;
var v2 = cc.misc.clampf(-1, 0, 20); //  0;
var v3 = cc.misc.clampf(10, 0, 20); // 10;

clamp01

限定浮点数的取值范围为 0 ~ 1 之间。

参数列表

• value Number

示例

var v1 = cc.misc.clamp01(20);  // 1;
var v2 = cc.misc.clamp01(-1);  // 0;
var v3 = cc.misc.clamp01(0.5); // 0.5;

lerp

Linear interpolation between 2 numbers, the ratio sets how much it is biased to each end

参数列表

• a Number number A
• b Number number B
• r Number ratio between 0 and 1
