LUA Scripting: Issue with getting slice data

[quentin_schmidBRKQZ]

Hi,

I am trying to get the area of a given slice. I tried this :

''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

local LayerThickness = 1.0;

local layerRecoatTime = 10.0;

local contourLaserScanSpeed = 900.0;

local hatchLaserScanSpeed = 1100.0;

local hatchDistance = 0.1;

local hl = 2.0;

system:setloggingtooglwindow(true);

local Nl = slicetray.layercount;

for i=0, Nl-1 do

Si = slice.calculateslicearea(sliceindex:i);

end;

''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

As it is indicated in the documentation, but it yields the error 

'''''''''''''''''''''''''''''''

2025-02-27 16:37:27;LUA Syntax Error: [string "ComputeBuildTimeEstimate.lua"]:14: function arguments expected near ')';General

''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

thanks

Hello,

That's a typo.

slice.calculateslicearea, with a period, tries to access the method as if it was a property, but it's not and as such needs a colon: slice:calculateslicearea()

Plus, sliceindex:Int in the documentation means that the single parameter the method expects is an integer. (Not because Lua requires it but because you can't have fractional layers.) The method's parameter doesn't actually have a name; that's just there for the reader to tell for what the method wants that parameter. So, for your example, you'll want slice:calculateslicearea(i).

Best regards,
