Is it possible to disable arrow-key camera panning?

[Fingolfin]

Well, that's about it. Is it possible to disable the built in camera panning that warcraft has?

I've done a system wherethe arrow keys are used for other things, but the camera is not locked to anything and should be pannable through moving the mouse. Therefore i don't want the camera to fly away everytime an arrow key is pressed. All help is appreciated.

Thanks.

as far as I know, you cannot disable it on free cameras but you can make it look like that,

but you need to know how fast the camera moves when you press a button, then do a trigger which if you press that button, you pan the camera to a location that will negate the effect (not the current position because that would bug if you press a key plus scroll using a mouse)

example: if the camera's speed is about 1000 units per second, then if you press a key, move it to a location 1000 units on the other direction...

Note: this is just hypothetical, I haven't tested it myself so I dont know if it would work fine...

That is a pretty OK idea, i wll try it out. Might turn out choppy, but it's better than nothing. Thanks.

It might have been pointed out (I can't bother to read), but you could always lock the camera to a specific point every 0.01 seconds (or 0.04 which I highly recommend as it isn't a too high value and it isn't as laggy as 0.01).

Won't those suloutions make the camera fixed to one position?
The concept of my system is to be able to use the arrow keys to manipulate the camera zoom and rotation, while you use the mouse to pan it around.
To freeze camera movement while pressing the keys is a pretty good suloution though, it will certainly work, although it might turn out a bit stiff.
If there is a way to negate the movement of the arrow keys i'd be very glad, though otherwise i guess i'll use GhostThrusters idea.

My trigger is just an example. Make another trigger that detects the release of the arrow keys, and unlock the camera from the point and remove that unit (camera_unit[Player Number]).

Theres a way to stop camera panning without locking it, i made it in a map before ill upload it in a second. I think that should work

• Test
  • Events
    • Map initialization
  • Conditions
  • Actions
    • For each (Integer A) from 1 to (Number of players), do (Actions)
      • Loop - Actions
        • Set Players = (Player((Integer A)))
        • Trigger - Run Test1 <gen> (ignoring conditions)
        • Trigger - Add to Test1 <gen> the event (Player - Players Presses the Left Arrow key)
        • Trigger - Add to Test1 <gen> the event (Player - Players Presses the Right Arrow key)
        • Trigger - Add to Test1 <gen> the event (Player - Players Presses the Down Arrow key)
        • Trigger - Add to Test1 <gen> the event (Player - Players Presses the Up Arrow key)

• Test1
  • Events
  • Conditions
  • Actions
    • Set Point = (Target of current camera view)
    • Camera - Pan camera for Players to Point over 0.00 seconds

omg, i'm waiting eagerly!

 

[InfinateAnswers]

i put it in my other post

 

[Garfield1337]

Your solution doesn't work at all,InfinateAnswers. It puts the camera where it already is after being moved.
Not to mention it doesn't work for multiple players...

Unless you have tested it, dont say it doesnt work. Btw "Players" is a variable

 

[Garfield1337]

• Set Point = (Target of current camera view)

You'll need to retrieve this locally to make it MPI.
Also i have tested it.

 

[InfinateAnswers]

Then fix my trigger. Mr. know-it-all

 

[Garfield1337]

I'll not fix it. I'm making new one.

EDIT: Well,there's problem. Warcraft registers arrow key press with a delay,which means it doesn't stop the camera immediately.
By some examination,it seems that IA's solution would work,but to make it MPI,you need to make it this way:

• Custom script: if GetLocalPlayer() == GetTriggerPlayer() then
• Set Point = (Target of current camera view)
• Custom script: endif
• Camera - Pan camera for (Triggering Player) to Point over 0.00 seconds

The problem is that is stops the camera after a delay of say half a second thus it moves camera a bit and that's unfixable,as far as i know.
If you want camera to pan back where it was,you can use script i wrote now,however it still has delay as first solution.

Just copy this text in a trigger and make variables: X (real array),Y (real array),CamForce (PlayerGroup) in variable menager if you want to use it.

Thank you garfield, it worked perfectly. Very ambitious to include a jass suloution aswell, although i ended up making my own one.

+rep, and thanks to all the others who helped.
