How to connect a floatField to a variable?

Question

I am working on a script where I need to connect a floatField to a variable that is called in a function. I have tried a connectControl but it still errors out and will not work. Any suggestions?

This is my UI block

##### UI #####
def createUI ():
    # Delete
    if cmds.window("TerrainUI", exists= True):
        cmds.deleteUI("TerrainUI")
    cmds.windowPref( 'TerrainUI', remove=True )
    # Create Window
    window=cmds.window ("TerrainUI", title="Terrain UI", w=350, h=750, mnb=0, mxb=0, sizeable=0)
    mainLayout=cmds.columnLayout(w=300, h=750,cal="left")
    ### Make Stuff ###
    cmds.button(label="Cleanup",w=300,h=25,c=cleanup)
    cmds.button(label="Create Viewport Lights",w=300,h=25,c=createViewportLights)
    cmds.button(label="Create Render Lights",w=300,h=25,c=createRenderLights)
    cmds.button(label="Create Plane",w=300,h=25,c=createPlane)
    cmds.rowColumnLayout( numberOfRows=16 )
    ## NOISE CONTROL ##
    cmds.text(label="Threshold")
    thresh=cmds.floatField( minValue=-1, maxValue=1, precision=4, step=.01 )
    #cmds.connectControl(thresh,"t")
    cmds.text(label="Depth Map")
    depmap=cmds.floatField( minValue=-1, maxValue=1, precision=4, step=.01 )
    #cmds.connectControl(depmap,"dm")
    cmds.text(label="Size Randomization")
    sizeran=cmds.floatField( minValue=-1, maxValue=1, precision=4, step=.01 )
    #cmds.connectControl(sizeran,"sr")
    cmds.button(label="Create Noise",w=300,h=25,c=noise)
    cmds.button(label="Color Plane",w=300,h=25,c=colorPlane)
    cmds.button(label="Create Trees",w=300,h=25,c=makeTree)
    cmds.button(label="Color Trees",w=300,h=25,c=treeShade)
    cmds.button(label="Create Mushrooms",w=300,h=25,c=makeMush)
    cmds.button(label="Color Mushrooms",w=300,h=25,c=mushShade)
    cmds.button(label="Create Clouds",w=300,h=25,c=makeCloud)
    cmds.button(label="Color Clouds",w=300,h=25,c=cloudShade)
    cmds.button(label="Create Moon",w=300,h=25,c=makeMoon)
    cmds.button(label="Color Moon",w=300,h=25,c=moonShade)
    # Show Window
    cmds.showWindow(window)

And this is the function giving me issues

def noise(t,dm,sr):
    if cmds.objExists("noise*"):
        cmds.delete("noise*")
    cmds.select("terrain_plane")
    cmds.textureDeformer(en=.9, s=1.5, o=0, d="Normal", ps="World")
    cmds.rename("textureDeformerHandle1", tPfx+"deform")
    cmds.shadingNode('noise', asShader=True)
    cmds.setAttr ("noise1.threshold", t)
    cmds.setAttr ("noise1.depthMax", dm)
    cmds.setAttr ("noise1.sizeRand", sr)
    cmds.connectAttr ("noise1.outColor", "textureDeformer1.texture")

Any help would be appreciated. Thanks!

Can you also paste the error message it outputs from the script editor? — Green Cell, Nov 05 '18 at 02:16

so you want to pass variables into ui. This is a big topic and the main answer is to use lambda or partial : Using Sliders in Maya with Python to control Shapes - intSliderGrp

from functools import partial

def noise(t,dm,sr, *args):
    # * args is used to skip default arguments passed by maya ui (a boolean pass as last)
    if cmds.objExists("noise*"):
        cmds.delete("noise*")
    cmds.select("terrain_plane")
    cmds.textureDeformer(en=.9, s=1.5, o=0, d="Normal", ps="World")
    cmds.rename("textureDeformerHandle1", tPfx+"deform")
    cmds.shadingNode('noise', asShader=True)
    cmds.setAttr ("noise1.threshold", t)
    cmds.setAttr ("noise1.depthMax", dm)
    cmds.setAttr ("noise1.sizeRand", sr)
    cmds.connectAttr ("noise1.outColor", "textureDeformer1.texture")

# with partial you can pass your three arguments.
# it is written partial(function, argument1, arguments2, ....etc)
button = cmds.button(label="Create Noise",w=300,h=25, c=partial(noise, t, dm, sr))

for more information go to the topic i linked above, if you have still questions, don't hesitate, cheers !
