Rpg Like Camera -

09-02-2009, 07:40 PM

Hi :D,
after a few days and a few questions here in the forum, i have finally done my rpg like camera :D
This camera is a 3rd person similiar to wow( world of warcraft)

Futures:

Camera is affacted by ground level, wich means if the hero goes up - so is the camera.

Ability to Rotate camera right, left. Using the arrow keys.

Ability to change angle of attack up, down. Using the arrow keys.

A smooth movment.

The distancce to target is changeable, by Typing: "V [number from 0 to 9999].
And also the height is affacted by the distance wich makes your hero always visible, even if you put 3000 distance, unless your already seeing black :D.

Also works by variable: Hero[1~6] (unit variable).
so to add this to map, you can easly import it and just set each player's hero. and it all works.
Here are the codes:

CameraScript:

JASS:

function SetCameraZ takes real z, player p returns nothing
    if GetLocalPlayer() == p then
       set z = GetCameraField(CAMERA_FIELD_ZOFFSET)+z-GetCameraTargetPositionZ()
       call SetCameraField(CAMERA_FIELD_ZOFFSET,z,- 0.01)
       call SetCameraField(CAMERA_FIELD_ZOFFSET,z,0.01)
    endif
endfunction

The Main triggers:

Trigger:

OverAll

Events

Time - Every 0.10 seconds of game time

Conditions

Actions

Player Group - Pick every player in (All players) and do (Actions)

Loop - Actions

Camera - Lock camera target for (Picked player) to Hero[(Player number of (Picked player))], offset by (0.00, 0.00) using Default rotation

Camera - Set (Picked player)'s camera Distance to target to (Real(CameraDistance[(Player number of (Picked player))])) over 0.10 seconds

Camera - Set (Picked player)'s camera Angle of attack to (Real(CameraAngle[(Player number of (Picked player))])) over 0.10 seconds

Camera - Set (Picked player)'s camera Rotation to ((Facing of Hero[(Player number of (Picked player))]) + (Real(CameraRotation[(Player number of (Picked player))]))) over 0.50 seconds

Set Loc[(Player number of (Picked player))] = (Position of Hero[(Player number of (Picked player))])

Custom script: set udg_TerrainHeight[(GetPlayerId(GetEnumPlayer()))+1] = GetLocationZ(udg_Loc[(GetPlayerId(GetEnumPlayer()))+1])

Set CameraHeight[(Player number of (Picked player))] = ((Integer(TerrainHeight[(Player number of (Picked player))])) + (CameraDistance[(Player number of (Picked player))] / 4))

Custom script: call SetCameraZ (udg_CameraHeight[GetPlayerId(GetEnumPlayer())+1] , Player(GetPlayerId(GetEnumPlayer())))

Trigger:

Distance

Events

Player - Player 1 (Red) types a chat message containing v as A substring

Player - Player 2 (Blue) types a chat message containing v as A substring

Player - Player 3 (Teal) types a chat message containing v as A substring

Player - Player 4 (Purple) types a chat message containing v as A substring

Player - Player 5 (Yellow) types a chat message containing v as A substring

Player - Player 6 (Orange) types a chat message containing v as A substring

Conditions

Actions

Set CameraDistance[(Player number of (Triggering player))] = (Integer((Substring((Entered chat string), 3, 6))))

*it's not all triggers, there is also the triggers for controling the camera movment using the arrow keys, sadly it's too much to add and i am short on time at the moment.

i need to credit some people for this, with out them i couldnt have done it, i don't remember who they are exactly so, if u do see this and u know u helped me, just tell me, i'll rep you and write ur name down here :D.

I am interested in making an rpg with this camera, if some one is interested too, tell me.

Link to map, check it out :D:

Anitarf	You'd probably get more replies if you posted your code instead of the map.

Hidden information:

(the hero is at the bottom of the cliff)

Also, you can't click on the minimap to move there because of the lock-to-hero.

Not to sound like a dick but:
"Camera is affacted by ground level, wich means if the hero goes up - so is the camera." I didn't notice this at all (see screen shot)

"A smooth movment." You're joking right?

"Also works by variable: Hero[1~6] (unit variable)." Kinda silly that you have to use that variable, guess I'm just too used to Oppi's one.

Just tested and it's way worse, locking camera to target is so skippy compared to panning to them. It also doesn't have any anti-clipping which results in lameness like this

Yeah, I rock.

Actually the cam looks pretty good for a GUI camera. Reminds me of the old days when OppiCam was still in GUI. It's the first time I see Toadcop's anti-smoothing function in action though and I have to say it's kinda jerky. When walking steep hills the camera is a bit laggy which doesn't look very natural. This is how I did it:

JASS:

        call MoveLocation(Loc, newx, newy)
        call SetCameraField(CAMERA_FIELD_ZOFFSET, GetCameraField(CAMERA_FIELD_ZOFFSET) + GetLocationZ(Loc) + Z_OFFSET + GetUnitFlyHeight(Unit[p]) - GetCameraTargetPositionZ(), duration)

Keep up the work. The camera system is what I learned Jass with and so will you.

Ive been having some problems with it too. Although, those problems might have been partly caused by too big far z values.

There shouldn't be any problems with far z other than it being capped at 10000 and causing a lot of lag at low camera angles.

Mendel	Opossum, thx :] Could u tell me exactly what to do to make it better?, i don't know jass at all :D that thing u wrote in jass doesn't tell me anything hehe ^^

To make it really good you should learn Jass. I won't teach you that as it's quite a goal to achieve.
Considering the camera's offset you should replace your jass function with this:

JASS:

function SetCameraZ takes real z, player p returns nothing
    if GetLocalPlayer() == p then
        call SetCameraField(CAMERA_FIELD_ZOFFSET, GetCameraField(CAMERA_FIELD_ZOFFSET) + udg_TerrainHeight[(GetPlayerId(p))+1] + z + GetUnitFlyHeight(udg_Hero[p]) - GetCameraTargetPositionZ(), 0.1)
    endif
endfunction

You can leave out the yellow part if you don't want the unit's flying height to be added.
Maybe Toadcop's version will not look that jerky if you use a bigger value than 0.01 for the panning duration.

Also you are leaking a location in your periodic trigger which will - in a 0.1 periodic trigger - cause the game to lag after some time. You should replace this line:

Trigger:

Set Loc[(Player number of (Picked player))] = (Position of Hero[(Player number of (Picked player))])

with this:

JASS:

call MoveLocation(udg_Loc[GetPlayerId(GetEnumPlayer())+1], GetUnitX(udg_Hero[GetPlayerId(GetEnumPlayer)]), GetUnitY(udg_Hero[GetPlayerId(GetEnumPlayer)]))

And this is exactly why I said you will learn Jass by improving this system.

Mendel	I need the 1.24 patch for this? JASS: call MoveLocation(udg_Loc[GetPlayerId(GetEnumPlayer())+1], GetUnitX(udg_Hero[GetPlayerId(GetEnumPlayer)]), GetUnitY(udg_Hero[GetPlayerId(GetEnumPlayer)])) cause i did replace and it just moves me to menu

09-03-2009, 04:56 PM	#11
Opossum	My mistake: JASS: call MoveLocation(udg_Loc[GetPlayerId(GetEnumPlayer())+1], GetUnitX(udg_Hero[GetPlayerId(GetEnumPlayer())]), GetUnitY(udg_Hero[GetPlayerId(GetEnumPlayer())]))

Mendel	ok, i did but now, the camera doesn't move on the Z line, :\ Edit: what does this movelocation do?

Instead of creating a new location it just moves an existing location to new coordinates. Doing this, you don't have to remove locations to avoid leaks.

What do you mean by "move on the Z line"? It might be possible that you need to initialize the location first:

Trigger:

Set Loc = (Point(0.00, 0.00))

Put that somewhere in your initialization trigger.

Mendel	he, i found the problem, we needed to put +1 in that getunitx and getunity arrays JASS: call MoveLocation(udg_Loc[GetPlayerId(GetEnumPlayer())+1], GetUnitX(udg_Hero[GetPlayerId(GetEnumPlayer())+1]), GetUnitY(udg_Hero[GetPlayerId(GetEnumPlayer())+1]))

Viikuna-	Man, I just wish that destructibles had vertex color, so I could use them instead of doodads and then turn everything transparent that comes between the camera unit and the camera.. In jass player ides go from 0 to 11. Player(0) is red, Player(1) is blue, etc.
