Issue creating multiple shaders with the same file

[Overkillz]

Hello dear community. Im currently trying to create multiple shaders using the same file.

In fact they are created but with the same values. For example. To the second shader I set it a different colour but when I draw it, practically has the same value as the first one. Other issue is that sometimes one of the both shaders isn't draw. I can't really remember why because I have tested it few days ago. Anyways, the goal of this topic is that you could help me to fix it or give me some tips to reach the goal.

currentHealth = 0
currentNos = 0

function startDrawing()
	dxDrawImage( 100, 350, 300, 300, myShader,0,0,0,tocolor(40,220,40,255)  )
	dxDrawImage( 450, 350, 300, 300, myShader2,0,0,0,tocolor(255,0,0,255)  )
	local theVehicle = getPedOccupiedVehicle(localPlayer)
	if theVehicle then
		local theHealth = getElementHealth(theVehicle) or 0
		local theNos = getVehicleNitroLevel(theVehicle) or 0
		currentHealth = (theHealth-250)/750
		currentNos = theNos
	else
		currentHealth = 0
		currentNos = 0
	end
	dxSetShaderValue( myShader, "degrees", currentHealth*180 )
	dxSetShaderValue( myShader2, "degrees", (currentNos*180) )
end

function startShadeing()
	myShader = dxCreateShader( "ring/Circle.fx" ) --Health
	myShader2 = dxCreateShader( "ring/Circle.fx" ) --Nos
	myTexture = dxCreateTexture( "ring/emptyCircle.png" )
	
	dxSetShaderValue( myShader, "tex", myTexture )
	dxSetShaderValue( myShader2, "tex", myTexture )
	
	dxSetShaderTransform(myShader2,180,180,0)
	
	dxSetShaderValue(myShader, "rgba", 0/255, 255/255, 40/255,1)
	dxSetShaderValue(myShader2, "rgba", 0/255, 40/255, 220/255,1)
	addEventHandler("onClientRender",root,startDrawing)
end
addEventHandler("onClientResourceStart",resourceRoot,startShadeing)

Thanks for reading, best regards.

Afaik different shaders aren't linked.

The only thing I learned from shaders is that tocolor behaves different when using shaders. Put it on 255, 255, 255 and let the shader do the rest.

 

This might also giving some problems if the shader isn't handling it right:

currentHealth = (theHealth-250)/750

>>>> 0 health > -250 > / 750 > * 180 = -60

if currentHealth < 0 then
	currentHealth = 0
end

Sorry, currentHealth variable is defined rightly. I just did the code again and I forgot to add math.max

Respecting the shaders. Why should I put the shaders 255,255,255 ? It depends of the shader file and how it is coded or im wrong ?

I think that it depends on the shader. Because tocolor didn't work with the shaders I tried.

I didn't use tocolor to set it. I

I know, but you did both, so maybe that could have caused problems. I am not an expert with shaders, so everything is maybe this and maybe that.?
