Voxel Edits

This example script draws a line of voxels as the object its attached to moves around. To try it select the object in the hierarchy and move it with the transformation gizmos. Since its not needed on client this script only runs on the server side.

Currently the script creates voxels in the the global static voxel database. Scripts can also edit individual dynamic voxel data objects.

local self = {}

function self:Start()
end

--do this every frame
function self:Update(deltaTime)
    self:updateEdit()
end

function self:updateEdit()
    --if position has changed since last frame make line
    if self.lastPos ~= self.transform.pos then
        if self.lastPos then
            self:makeLine(self.lastPos, self.transform.pos)
        end
        self.lastPos = self.transform.pos
    end
end

--make a capsule from p1, to p2
function self:makeLine(p1, p2)
    --multiply thickness by transform scale
    local thickness = 0.1 * self.transform.scale
    local s = Capsule(p1, p2, thickness)
    local col = self:randomColor()
    VoxelEdit(s, col):Add()
end

--generate random color
function self:randomColor()
    return Vec3(math.random(), math.random(), math.random())
end
