The prototype looks like this:
float Utils.getDensity(id, channel, startWorldX, startWorldZ, widthWorldX, widthWorldZ, heightWorldX, heightWorldZ)

The id is the entity id of the terrain detail object. You can get it like this:
local id = g_currentMission.fruits[fruitId].id

Check out the documentation on ls-mods to get some info about the start/width/height parameters:
http://ls-mods.de/scriptDocumentation.php?class=utils



You can create a new checkbox with:
OverlayCheckbox:new(Overlay onOverlay, Overlay offOverlay, bool isChecked, func callbackFunctionWhenClicked, object callbackTarget);

and a button with:
OverlayButton:new(Overlay buttonOverlay, func callbackFunctionWhenClicked, object callbackTarget);

onOverlay, offOverlay, buttonOverlay are overlays which describe how the button/checkbox look like. You can create it with:
local onOverlay = Overlay:new(name, imagefilename, posX, posY, sizeX sizeY)

The callbackFunctionWhenClicked looks like this for the checkbox:
function className:callbackFunctionWhenClicked(isChecked)

end

The function for the button is the same without the isChecked parameter.

I have a similar question. How works the function "setDensityMaskedParallelogram"?

Pierre S (unknown) 28.09.2009 20:32
When you spray or seed or cut, you make a new texture over last texture !!

Exemple:

if you cut the maize, setDensityMaskedParallelogram replace texture with cuttedmaize in your file "fruit_density.grle" !!

setDensityMaskedParallelogram(cuttedMaizeID, x, z, widthDiffX, widthDiffZ, heightDiffX, heightDiffZ, 0, MaizeId, Chanel, 1.0)

it's the same things for texture cultivator !!

The difference between setDensityMaskedParallelogram and setDensityParallelogram is, that setDensityMaskedParallelogram only changes the value of the first id where the given maskId has some value != 0 in the channels firstMaskChannel to numMaskChannels.

Note that the sample code of Pierre S is missing the numChannels and numMaskChannels values. These are new in LS09. I think that this is some code from LS08.

The prototype looks like this:
setDensityMaskedParallelogram(id, x, z, widthX, widthZ, heightX, heightZ, firstChannel, numChannels, maskId, firstMaskChannel, numMaskChannels, value);

oh ok i understand the difference !! sorry for missing. yes its a code for ls08 !! i do not think this fonction change with ls09 ;)

thx for your answer.

Stefan, can you make a example to create e.g. grass_cut_long?

I dont know wich values for: 'id', 'firstChannel', 'numChannels', 'maskId', 'firstMaskChannel', 'numMaskChannels', 'value'
