Having trouble with 3rd person movement

[PrisonLove]

Hey, so I used the tutorial in the tutorials section to create a third person movement system for my zealot using mouse look and WASD movement. I've run into a major problem.

When moving, the Zealot will only face the camera yaw if it is in the bottom left quadrant of the map. It's very strange and I don't know why it's happening. I was also able to replicate the problem, it seems as if the unit just stops facing the camera yaw after it hits a certain x, y point in the map. The replicated issue is in the 3PMovementTest map.

Could someone help me with this issue? I'll post the map as well as the triggers I'm using.

• camTimer = (New timer) <Timer>
  • camPlayerGroup = (Empty player group) <Player Group>
  • camUnit = No Unit <Unit[16]>

I could have waited 14 minutes and you would've asked my same question. Brilliant.

I am having the same problem as your second problem. The camera yaw seems to stay at 90.0 no matter which way you move your camera with your mouse. Camera rotation seems to stay at 180.0 regardless of camera mouse movements as well. I don't know if this is a bug in the latest build or if I'm doing something wrong. I'm still trying different things and I'll post if I find something out.

 

[PrisonLove]

Very strange discovery. The movement system only works in a certain part of the map. It's very odd, but can anyone hypothesize as to why this is happening?

 

[Renendaru]

I can't seem to have your issue. I'm using just about the same system, though different in some areas. I'm setting camera values, and all work perfectly. Camera rotates, it's at the right settings and everything. So I am confused.

 

[Derek0]

Well I can't seem to find out the mouse/camera/facing problem, but as for your first problem, try turning on the "Play Forever" option instead of just using "No Options" for your animation trigger. Or did you find another way to fix it?

 

[PrisonLove]

I figured out the animation problem, thanks. I uploaded the map to the first post so that people can see. It's a bizarre thing. Move the zealot toward the opposite end of the map and after a while you'll see that he begins to not be able to turn around.

EDIT: just uploaded the newest version of the map. In this one it sets the Zealot's facing to the camera yaw everytime the timer expires. The problem is that the unit will only face the camera yaw when it is in the bottom left quadrant of the map. I don't know why this is. Is it bug? Has anyone else experienced this? Is it a mac thing (wouldn't surprise me). Can someone download the map and test it to see if they get this issue as well?

 

[PrisonLove]

BUMP: I was able to replicate the problem. I uploaded a 3PMovementTest map. In this map I divided it into quadrants using terrain tiles. You'll notice that if you go too far past your starting quadrant (lower left) the marine will stop facing the camera yaw. I tried it on multiple tilesets so it's not an issue with the tileset used. This map is a different size than the one I used for my main map (this one is smaller), so that lead me to determine that after the unit passes a certain x or y value on the coordinate plane, the unit stops adjusting to the yaw, not just when it leaves one quadrant of the map like in the SpaceBall map I have posted. Is this a bug with the editor or with my code?

Help please!

 

[Builder Bob]

I did a short test with your map to see what the readout of the camera yaw was. For some reason, it's not giving the right output in the areas you are describing. Totally weird...

I haven't done a lot of testing though. Maybe try to see at what x/y coordinates of the map the bug occures. Have you adjusted the size of the map after creating it? At first glance it looks like a bug to me, but maybe it has a natural explanation.

Edit: I have a pc. Not a mac issue

 

[PrisonLove]

For the 3PMovementTest map I adjusted the size of the map after creating it, but the problem existed both before and after the adjustment. For the SpaceBall map I did not ever adjust the map size after creation.

Thanks for testing, does anyone have a possible solution?

Edit: I was looking around the SC2 beta forums and other people have reported this issue with the latest patch. I suppose it's a bug that needs to be fixed by Blizzard, but if anybody else has a solution I would be glad to hear it.

Here is the link to the discussion: SC2 Beta Site

 

[Frozenwind]

It might lag, but try resetting the camera every time a movement occurs? Then it can't bug like this at least. Temporary solution until they debugged it. (So I recommend added comment tags so you know what you added as temp. solution).


Or make your map bigger (if possible) and only play in one quadrant of it. Might be a little bit lame though.

 

[PrisonLove]

Does anyone know if this was fixed in the retail version? Mine is on order so I won't have it for a few days, but I'd like to know.

 

[Derek0]

It started working on my map at least when I installed the retail version. I'm guessing it's fixed.

 

[PrisonLove]

All righty then, thanks.
