Where did you get pc.ARROW_UP from?

Thank you

i was trying it myself
this is similar to the ToString thing, but i was working with a dodge mechanism
if (this.app.keyboard.wasPressed(pc.KEY_Q) === true) {
this.entity.rigidbody.applyImpulse(0, 0.1, 1);
}
if (this.app.keyboard.wasPressed(pc.KEY_E) === true) {
this.entity.rigidbody.applyImpulse(0, 0.1, -1);
}
and it says
Couple of things:
-
this.appis undefined for some reason. The reason will depend on the surrounding code. - You don’t need to compare against
true. You can just do:
if (this.app.keyboard.wasPressed(pc.KEY_Q)) {
this is all of it }
}
};
if(this.app.keyboard.wasPressed(pc.KEY_Q));
this.entity.rigidbody.applyImpulse(0, 0.1, 1);
}
if(this.app.keyboard.wasPressed(pc.KEY_E)
this.entity.rigidbody.applyImpulse(0, 0.1, -1);
}
it say this 
You should not have a semicolon here:
if(this.app.keyboard.wasPressed(pc.KEY_Q));
Might I suggest this course to get more familiar with Javascript syntax?
but, it says Missing semicolon, unrecoverable syntax error(97% scanned)
You removed the incorrect semicolon.
Literally on this line above that (145):
if(this.app.keyboard.wasPressed(pc.KEY_Q));
You should not have a semicolon as you are declaring your if statement.

What about line 153? Is that semicolon also there by mistake?
no,it shows a red X
its supposed to be there
Without seeing your entire script, I am unable to provide you with a proper answer. Based on the the small amount of structure I can see, my guess is that a semicolon should not be there.

no.
