JavaScript code sharing for collision detection special effects and js Code for collision detection Special Effects

I encapsulated the collision detection by myself. Let's take a look at the demo of the instance and look at the encapsulation.

Function Encapsulation
Function isCrash (obj1, obj2) {var boolCrash = true; // assuming true is the collision var left1 = obj1.offsetLeft; var right1 = obj1.offsetLeft + obj1.offsetWidth; var top1 = obj1.offsetTop; var bottom1 = rows + obj1.offsetHeight; var left2 = obj2.offsetLeft; var right2 = obj2.offsetLeft + obj2.offsetWidth; var top2 = obj2.offsetTop; var bottom2 = rows + obj2.offsetHeight; if (right1> left2 & left1 <right2 & bottom1> top2 & top1 <bottom2) {boolCrash = true;} else {boolCrash = false;} return boolCrash ;}
