Transition Issue

[Jmarlin3]

I've been using this video as a tutorial:

In one part of the tutorial, he instructs us to code for the transition to another room. But when I enter through the room for the transition, the fade works, but this error appears:
FATAL ERROR in action number 1 of Draw Event for object obj_fade: Variable obj_fade.xx(100020, -2147483648) not set before reading it. at gml_Object_obj_fade_Draw_64 (line 10) - obj_player.x = xx; ############################################################################################ -------------------------------------------------------------------------------------------- stack frame is gml_Object_obj_fade_Draw_64 (line 10)

Although when I compare the code to the video, it's correct:
My code:

The videos code: (around the 13:26 mark)


I honestly don't see the issue here. I've watched the video a couple of times and haven't seen the issue.
Can someone please explain what the error means?

The error is telling you that you never gave xx a value.

Ok I get what you're saying, but where should I give it a value? In a create event? And I don't fully understand what xx means.

I have no idea man... re-watch watch the tutorial and see where they use it.

Hey I figured it out

I initialized it as

fade.fade_xx
fade.fade_yy

When It should've been

fade.xx
fade.yy

Thanks again!
