How to set same style to multiple elements with one line of code

[Anahit DEV 2]

Hello to all coders,

I need to add same styling to multiple elements/variables. How i can write the code/syntax in Phaser so i do that with one line of code not 100s lines for same thing. For example

 

basicTableJackpotSymbolOn.alpha = 0;
game.add.tween(basicTableJackpotSymbolOff).to({alpha: 1}, 500, "Linear", true);
basicTableBarSymbolOn.alpha = 0;
game.add.tween(basicTableBarSymbolOff).to({alpha: 1}, 500, "Linear", true);
basicTableMelonSymbolOn.alpha = 0;
		            	
basicBetYellowRectV2N3Point.fill = '#999999';
basicBetYellowRectV2N4Point.fill = '#999999';
basicBetYellowRectV2N5Point.fill = '#999999';
basicBetYellowRectV2N6Point.fill = '#999999';

 

Thanks in advance.

In Phaser , you can add sprites to a group and use setAll to change properties of those sprites, you can use forEach() or callAll() :

 

In general, to repeat certain code, you can use for loops.

Great. 

Thank you very much for the working snippet and advise.

Hey @samid737 

I was testing the code with some elements and noticed that after grouping they are changing their defined positions(x,y tec) so after grouping they appear not in their previously defined positions.

Any way of avoiding this issue please?

Thanks in advance.

Normally that can happen if you change the position and pivot, scale or rotation of the group and then add a sprite. Try transforming the group after adding all sprites otherwise, you can try using world coordinates?

I tried with world @samid737 but is not really working. What you mean by

Cant i just group them without changing anything in their current parameters?

Thanks

Transforming is rotating scaling, positioning/moving your group. Yes you can definitely do that, but if you transform your group it might be that your sprites will not have the position that you pass as A parameter. This might not be your issue though. Do you have an example of your code?

Yes here it is @samid737

basicTableJackpotSymbol = game.add.sprite(0, 0, 'basicTableJackpotSymbol');
basicBetInnerWrapRect.addChild(basicTableJackpotSymbol);
basicTableJackpotSymbol.alignIn(basicBetLeftRectV1N2, Phaser.CENTER);
basicTableJackpotSymbol.frame = 0;

activateBasicPSymbols = game.add.group();
activateBasicPSymbols.addMultiple([basicTableJackpotSymbol,basicTableBarSymbol,basicTableMelonSymbol,basicTablePlumSymbol,basicTablePearSymbol,basicTableRaspberrySymbol,basicTableAppleSymbol,basicTableOrangeSymbol,basicTableLemonSymbol,basicTableCherrySymbol,basicTableSignSymbol], false);
activateBasicPSymbols.forEach(activateBasicPSymbolsFunc,this);
function activateBasicPSymbolsFunc(activatedSymbol){
	activatedSymbol.frame = 0;
};

My guess is alignIn displaces the sprite. If you have some fixed amount of sprites that need to be aligned in a grid, one idea is to re-arrange sprites using group.align() instead of the extra rectangle.
