Ok, i have messed alot with my door here, but i can't seem to get the door to open, when i get near. I think i have misunderstood how the startoffset and sensorray offset works. Is there anybody who could explain how it works? I mean the part about HOW it works, not offsets.

Mmm, that's a nice nonexistent attachment.

Anyways, as far as I understand it, here's how the Sensor Ray offset works.

So, the Open Offset, Closed Offset, and Open Closed Offset all originate from one point. I don't know what it actually IS, but, they are all one point. In this twisted offset, positive X moves you to the right, negative to the left, positive Y moves down, and negative moves up.

Now, Sensor Ray is an especially odd function. It draws a sensor area for the device using a line, which uses the two offsets available.

The offsets for the start and end points of this ray have the same origin as the Open/Closed/OpenClosed offsets.

Meaning that, if your door is, say, (0,0) closed and (0,48) open, a good sensor ray offset to use would be (24,-24) to (-24,-24). This would draw a horizontal line, which extends 24 pixels out from the door, 24 pixels into the air.

24 is used because it's the default tile size in CC.

Wohoo! Finally it worked! Time used on rest of mod = A morning. SensorRay offset = a day and a half
Thanks Grif.
