Help: Assigning Colliders to objects

[Caveman1217]

I need help!!

So i have been staring at example codes and tutorial for the past 4 hours and i still cant seem to get this thing to work. I am new to coding, but I have to learn in to keep up in my current job. If anyone has any suggestions or any pointers on how to make colliders work with this script I could use all the help i can get.

var game = new Phaser.Game(728, 1280, Phaser.CANVAS, 'Bombs_Away', { preload: preload, create: create, update: update, render: render });

function preload() { 
    game.load.atlas('assets', 'assets/Images/assets.png', 'assets/Images/assets.json', Phaser.Loader.TEXTURE_ATLAS_JSON_HASH);
    game.load.image('background', 'assets/Images/Background.png');  

  
}

function create() {
    
    game.physics.startSystem(Phaser.Physics.ARCADE);

    
        bg = game.add.sprite(0, 0, 'background');
        bg.width = 728;
        bg.height = 1280;
    
        sprite3 = game.add.sprite (-35, -190, 'assets', 'healthframe.png');
        sprite3.width = 300;
        //sprite1.hight = 5;
    
    
        herobase = game.add.sprite (0, 450, 'assets', 'herobase.png');
        game.physics.enable(herobase, Phaser.Physics.ARCADE);
        
   
        bomb = this.game.add.sprite (50, 0, 'assets', 'bomb');
        game.physics.enable( bomb, Phaser.Physics.ARCADE);
        bomb.body.velocity.y= 50 + Math.random() * 600;
        bomb.animations.add('fall', [0,1 ], 15, true);
        bomb.animations.play('fall');
    
       

        
        game.add.text(20,30, 'SCORE:', { font: "40px Impact", fill: "#ffffff" }); 
    

    
    }                    

function update(){
    
}

//function colliderHandler(obj1, obj2){
    

//}

function render (){
    
    
}
