Velocity is undefined

[nothing]

Console gives me this error:  TypeError: Cannot read property 'velocity' of  undefined. I don`t know what is wrong, thank you for everything.

[Théo Sabattié]

heroname = localx[i].load.name;

// ...

heroname.body.velocity.x = -250;

body is undefined.

so body property does not exist on heroname.

localx.load.name;

Does that return a complexe objet?

That name looks like returning a string
