Hi,
I am currently learning MAXScript for a university project and am having an issue with the rollout that I have created using information from MAXScript 101 tutorials. I have created the rollout and am having trouble with the code. I am aiming to have a Tree planter like the one in his video but without the curve. I can’t seem to get it to work and was wondering if someone could take a look at my code.
numTrees = 500
utility TreeGenerator “Tree Generator” width:207 height:343

local surf, master
GroupBox 'grp1' "GroupBox" pos:[9,8] width:184 height:104 align:#left

pickSurf.text = obj.name
surf = obj
)
on pickMaster picked obj do
(
pickMaster.text = obj.name
master = obj
)
on create pressed do
(
for i in 1 to numTrees do
(
local treePos = (intersectRay surf treeRay).pos,
treeScale = [1,1,1] * random fromScale.value toScale.value
instance master pos:treePos scale:treeScale name:"tree"
if mod i 10 == 0 then redrawViews ()
)
)
)
where is ‘treeRay’
So this is the updated script that I have got but I am still receiving an error ‘pos is undefined’.

)
)
pos in 1st different from 2cd
1st
treePos = (intersectRay surf treeRay).pos
this ray may be undefined
2cd
theNewTree.pos = [(random -200 200), (random -200 200), 1000]
this ‘theNewTree’ is a variable ，there is no ‘pos’ property with it , delete ‘.pos’ , will done
So the issue I am having now is the error: Unable to convert: (ray [-69,-30,0] [0,0,1] to type: Point3
This is the script I have currently:

local treePos = (intersectRay surf treeRay)
this is ray , not a point3 , like before , use ray.pos
