Methods

clampf

Clamp a value between from and to.

Parameters

• value Number
• min_inclusive Number
• max_inclusive Number

Examples

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

Clamp a value between 0 and 1.

Parameters

• value Number

Examples

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
