Creating a Camera System

[Cihparg]

Greetings, I'm trying to create a camera system, but I might need some help developing it.
The point of it is that it allows collecting X / Y data of the players camera, which can easily help creating a on-screen inventory system. ( Hopefully )

I am currently creating it in GUI, but still both Jass and GUI are welcome here, anyhow I do not allow vJass, DGUI, zinc or any similiar things in here.

If you are interested of helping me out with this, you can post suggestions, feedback and thelike to this thread ( or via Visitor Message ), so that I can update the script itself.

First template will come either today or tomorrow, be patient.

Yes, I am fully aware that the system uses local player content, yet I'm going to make it MPI.[/hidden]

Since you've already got your foot in the door (have a work in progress) this is OK to be in the Triggers & Scripts section (where I've moved it to)

 

[Cihparg]

Well then, I would like some feedback/suggestions because creating a system like this alone, is a pain.

 

[Bribe]

You are not alone, there are a lot of great camera systems and full-screen inventory systems out there which you can use as guidance.

 

[Cihparg]

Well, this system does not function like 90% of the others, infact, it could be 100% different than any in the internet already.
Currently I am rewriting the actual system to Jass, so that it can be used as a single-liner.

Infact, after I started to develop this, I couldn't call it much of a "Camera System", as it mostly just returns data from the player's camera, it does not move or enchant the camera itself.
Though, objects can be placed on the screen, and that works rather easily.
Once I find a way to function the units without causing a desync, this system is ready to go.

 

[Bribe]

It will always cause a desync, getting data from a player's camera and using it to do something like SetUnitX or whatever. It would have to be a single-player fullscreen inventory if you plan to get that kind of data.

 

[Cihparg]

Are you sure about that ?
Also, this thread is quite becoming a discussion between us two at this moment, might want to continue on either VM or PM.

But, it should be possible if you for examble~ Use GetLocalPlayer() to make sure the unit is the local players ? The only issue atm is using functions to move a unit, or do anything with a unit with local content. Displaying the data for each player does not cause a desync.

I believe if you can make a condition to check if the unit is owned by the local player, it should not cause a Desync.
As I am new with Local Player, here is just a examble of how it could work, it might not work.

function checkUnitForLocalPlayer takes unit oUnit returns unit
local player oLocalPlayer2 = GetOwningPlayer( oUnit )
if ( GetLocalPlayer() == oLocalPlayer2 ) then
return null
else
return oUnit
endif
endfunction
// Yes, this most likely would create a Desync.
// Infact, it would create a Desync.

EDIT: Hmm, yes, I do now see why it is Impossible, but, I will research this no matter what.
