Camera Help

[ShadowSnipe4]

I'm trying to get it so that the camera is put 32 units in front of "MoveUnit" and i have the camera script line that's giving me problems right here.

call SetCameraTargetControllerNoZForPlayer( Player (currentPlayer), udg_MoveUnit[currentPlayer + 1], 0, 0, true )

how would I get it so that it is just in front of the unit?

 

[AceHart]

Point with polar offset: position of unit offset by 42 in direction "facing of unit".

 

[ShadowSnipe4]

How would i incorporate that into the camera trigger though?
My problem was that it has only spots for the x and y axises no polar offset.

 

[AceHart]

Hm... the simplest is probably to move a dummy unit at that spot and lock the camera on the dummy.


Other than that, well, there's some formulas:
x = distance * cosine(facing of unit)
y = distance * sine(facing of unit)

I have no idea though whether those produce the correct results in all 4 quadrants...

okay, I give up trying to do this on my own. Can anyone figure out why this isnt working? Its supposed to make the camera just in front of the unit at all times, but it doesnt work, it sometimes make the camera go underground, and sometimes over the walls, also with this on the hero wont move anymore, I think it has something to do with the actual camera dummy unit but its been giving me problems also.

Fogot to put the spawn trigger.

The variables i have in gui are: CameraUnit-Unit Array[10]-none-, MoveActive-boolian array[10]-false-, MoveActiveLeft-boolian array[10]-false-, MoveActiveRight-boolian array[10]-false-, MoveUnit-unit array[10]-none-.

if someone actually reads all of that and has an answer, I would greatly appreciate it.

EDIT: Also, theres a problem with going foreward right and foreward left. Its under the "Hero Movement" part.

My God...you expect someone to read ALL that?

[ShadowSnipe4]

I hope for someone to, I've been failing at getting this to work properly for days now. (the camera part at least)

You guys, thanks to whoever actually read all that but I GOT IT TO WORK!!! I cant believe that that entire time its because I set the unit for cameraUnit to the maring and the unit for moveUnit to the camera dummy...

Also, is there a way to set the camera Z offset? Its a little too close to the ground.
