SetStatic gives an error

Phaser 3
1

Hello, I am new to phaser. I want to set a body to change a dynamic body to a static body if certain conditions are met. I created a simple example to try to get it working but without luck:

class NormScene extends Phaser.Scene {
constructor(config) {
super({ key: ‘NormScene’ })
this.config=config;
this.ball = null;
}

preload()
{}

create() {

    let circle = this.add.circle(200,110,50, 0x00FF00 );
    let body = this.matter.add.circle(200,110,50,{
        isStatic: false,                             
    }) ;
    this.ball = this.matter.add.gameObject(circle,body);
}

update(time, delta) {
 
    if(time>1000){
        this.matter.body.setStatic(this.ball, true);
    }
}

}

the error I get is:

Uncaught TypeError: Cannot read properties of undefined (reading ‘length’)

Ok figured it out after a good night sleeping :slight_smile:

this.matter.body.setStatic(this.ball, true);

should be

this.matter.body.setStatic(this.ball.body, true);
