multiple sliders

Hello,

Hopeing there is a simple answer this this, but how do you distinguish between four sliders so that each slider alters a separate parameter.

I have 4 sliders sliderSWRD, sliderSWEX, sliderRTRD, sliderRTEX set at the four corners of my screen. When I use the follwing code to detect a response from say SWRD and change a parameter it works fine; however, responding with any of the other sliders also changes that parameter and I don't want this to happen.

HTML Code:
def reponse():
	global radadj, radius, adjustswing, swingmiddle
	def myslider(sliderSWRD, pos):
		adjustswing=swingmiddle-pos
		def onMouseDown(button):
			if button == viz.MOUSEBUTTON_RIGHT:
				radius=radius+adjustswing
				sliderSWRD.disable()   ### re-enabled elsewhere
		viz.callback(viz.MOUSEDOWN_EVENT,onMouseDown)
	viz.callback(viz.SLIDER_EVENT,myslider) 
Any tips would be useful, sure I'm missing something obvious. Thank you.

You need to check that the slider object passed to the callback function is sliderSWRD before changing that parameter:
Code:
def onSlider(obj,pos):
    if obj == sliderSWRD:
        #change parameter

viz.callback(viz.SLIDER_EVENT,onSlider)
You can also use the vizact.onslider command to call different callback functions based on which slider was changed:
Code:
def onSliderSWRD(pos):
	#do something
	
vizact.onslider(sliderSWRD,onSliderSWRD)

def onSliderSWEX(pos):
	#do something
	
vizact.onslider(sliderSWEX,onSliderSWEX)
