translate/rotate speed on a moving entity, issues in 2.0x

[PranQster]

I loaded up Siegeshop the other night in TDM 2.02 and discovered that the chains supporting the drawbridge did not translate to the proper position when opening the bridge. They were positioned worse upon closing the bridge.

I loaded up one of my early test maps in which I originally built the drawbridge, and it showed the same improper translation behavior. The chains were many units away from where they should have been after 15 seconds translation. But then I noticed that they were still moving, albeit very very slowly. After about 5 minutes the chains settled into their proper position, attached to the drawbridge as they should be.

That translation which took 5 minuted should only take 15 seconds. The entities never changed (I tried 3 different maps with the same drawbridge entities), but something in TDM did. Any ideas?

 

I also have tested the same issue in 2.03 with the same result.

Confirmed. No clue why it changed, though.

 

I'll have to dig up a 2.00 or 2.01 installation to see how it behaves there.

 

Filed a bugtracker for it.

Thank you.

It appears that rotation is correct, but the chains aren't translating.

I found the problem, which was a bug fix I put into 2.02 for interrupted, translating doors not closing properly.

 

According to that math,the chains wanted to take 22 minutes to reach their final position, which is why they were moving so slowly once the drawbridge had come down.

 

Corrected.

Wow 22 minutes. Cool, thanks for finding the issue.

Corrected.

I'm curious, what kind of mistake was made?

The chain is a door.

 

There are two origins kept for a door: a local one and a global one.

 

I was using the global one instead of the local one.

 

In the instance of a normal rotating/translating door, this didn't matter.

 

Because the chain was also bound to the moving drawbridge, it did matter.

 

Switching from the global origin to the local origin didn't change the behavior of a normal door, but it did change the behavior of the chain, correcting it.
