How set a value in $gameScreen._pictures[] [solved]

[Jonforum]

Hi guys.
I did succeed to set value to a array X,Y value.


I try to set definitely the ._originX of the ex: $gameScreen._pictures[1]


I try this 


 $gameScreen._pictures[1]._originX=800;


or 


 $gameScreen._pictures[1]._originX.setValue(800);


Nothing work


Its Alway reset to default ??


Ex: here, i need to definitely change the value 


_originX:400
_originY:400


To another valur


 there is a particular syntax?

Game_Picture {_name: "suny-2", _origin: 0, _x: 340, _y: -80.00000048000004, _scaleX: 100…}
_angle: 0
_bindToMap: 1
_blendMode: 0
_duration: 0
_height: 375
_horSpacing: 2400_layer: "above_characters"
_loopHeight: 4800
_loopWidth: 4800
_mapOffsX: 0
_mapOffsY: 0
_name: "suny-2"
_opacity: 255
_origin: 0
_originX: 400
_originY: 400
_rotationSpeed: 0
_scaleX: 100
_scaleY: 100
_targetOpacity: 255
_targetScaleX: 100
_targetScaleY: 100
_targetX: 400
_targetY: 400

Perhaps you should explain why exactly you want to do that?


I could understand if you want to change _x and _y to move the picture, or scaling to resize it, but why change the origin? that doesn't make any sense to me...

Its hard to me to explain.


In basic, i have planet rotate.
When click galaxi
This move and zoom, but need to bind planet befor move and zoom.
When i try bindpictures( all planet)


They bind to original 


_originX: 400
_originY: 400


So i need to set 



EX: 


CurrentX = $gameScreen._pictures[1]._x // Exampel this give 800


$gameScreen._pictures[1]._originX = (CurrentX);


And after i use 
this.bindPictureToMap(1, 1, 'above_characters');


But after i bind my picture, the  ._originX and ._originY Reset default value (400)!!!!


I made little video to show you what am trying to do.
If you have some other idea is welcome


When i clic, i need save all ._X and ._Y, and inject in all ._originX   ._originY Permanently

yes, I understand what you want to do. Unfortunately that is not something as easy as a changing of the origin suggests.


Sorry - I'm too exhausted at the moment to really think it through, but I think you'll need three coordinate systems with three origins to pull this off, precisely because the computer needs an unchanging origin to keep everything fixed. There might be a way around that with some fancy mathematical transformation, but I can't even point you in the correct direction at the moment.

ok ok thanks anyway friend



I'll see if I can find another direction and approach, but I spending more than 3 hours to reflect and am locked.

Ok it solved! 


I used the wrong function as a beginner


$gameScreen._pictures[Planet5PID]._originX = ...


instead of this


the good way !


$gameScreen.picture(Planet5PID)._originX = ....


So this is awesome, because, you can easy move a bind picture in a parallel process !!!


this.bindPictureToMap(Planet5PID, 1, 'above_characters'); // Bind to wrong pos
var TMp1x = ($dataMap.events[3].x*48) + Math.cos(g3p1angle) * (g3p1radius*2.5); // galaxi, planet, posX // calculate true moved posx
var TMp1y = ($dataMap.events[3].y*48) + Math.sin(g3p1angle) * g3p1radius; // galaxi, planet, posY // calculate true moved posy
// Inject the true last moved pos X,Y in the ._originX
$gameScreen.picture(Planet5PID)._originX = TMp1x; // move the bind to good X pos
$gameScreen.picture(Planet5PID)._originY = TMp1y; // move the bind to good y pos


so it's good to know, to move a binded picture, simply increments the variable in
._originX, ._originY


with 


$gameScreen.picture( )._originX


Tanks all for help
