[Solved - NavMesh Problem]

I have a script which adds blocks to order to make a level, but it won't supply a working Navmesh. I have reworked it to the script on the website, but DebugNavigatioMode shows no blue area.

 

This is the script for each box

 

width = 2.56
height = 1.28
depth = 2,56

local sc = Vec3(width,height,depth)
local m = Model:Box()
local s = Shape:Box()
m:SetShape(s)
s:Release()
m:SetScale(sc)

m:SetNavigationMode(true)

 

Shouldn't this, when using world:BuildNavmesh, be enough to create a navmesh in game? Each side is only 2.56 long so it is not the edge length. Characters also have navigation mode enabled but there is no blue area even.

 

Edit - It works on a test box, nut not on the script I have written that creates multiple boxes and then builds the navmesh. I will keep working on it but if anyone has any tip on building navmeshes from script it would be much appreciated

 

 

Solved - the objects parents were not set to navigation mode, so the hierarchy was upset

[animation import issue]

I have this model but the mesh doesn't attach to the armature, can anyone explain this for me? it is a blender model with the new importer used but the preview doesn't give action for the mesh

[SetVertexPosition not registering]

thanks macklebee i thought it was something like that

[SetVertexPosition not registering]

I am working on an imported fbx model and i want to adjust the physical appearance in real time, but the functions for setting vertex positions do not have any visible effect on the model. Is this code wrong or is it not implemented in lua or what? thanks for your interest

 

 

local v = vertex

self.hits = self.hits + 1

local sfc = self.entity:GetSurface(0)

local vp = sfc:GetVertexPosition(v)

local vn = vp:Normalize() * 0.5

local offset = vp + (Vec3(0) - vn)

sfc:SetVertexPosition(v,offset)

self.entity:UpdateAABB(self.entity.LocalAABB)

self.entity:UpdateAABB(self.entity.GlobalAABB)

self.entity:UpdateAABB(self.entity.RecursiveAABB)

System:Print(vp)

System:Print(offset)

[I am missing GetTriangleVertex? [solved]]

Thank you Josh

[I am missing GetTriangleVertex? [solved]]

there are no triangles on the internal model either in the global pickinfo, although when i counttriangles there are 480

[I am missing GetTriangleVertex? [solved]]

I have tried that now but it has no triangle at all now. I will look in to it.

 

Edit

 

Is it possible to find a triangle on a pick entity that is imported? the triangles might not register in the same way, as when i made the pickinfo global and tried the impact on two places the triangle variable stayed at 0. I will try it on a internal model

[I am missing GetTriangleVertex? [solved]]

its come up -1, you are right. Is it normally a simple process with a Pick triangle? It should come back with the triangle integer according to the PickInfo section.

this is the pick script

 

 

w:Pick(b,b + d,pk,3,true)

if pk.entity ~= nil then

local v = pk.entity:GetKeyValue("mining","")

if v == "true" then

pk.entity.script.hitmark = pk.triangle

pk.entity.script.srfc = pk.surface

pk.entity.script.hitnorm = pk.normal

System:Print(pk.entity.script.hitmark)

end

local v = pk.entity:GetKeyValue("hit","")

if v == "false" then

pk.entity:SetKeyValue("hit","true")

end

 

would it be more than one with that radius? - edit

end

[I am missing GetTriangleVertex? [solved]]

here is the code

 

for i = 0,2 do

local v = self.srfc:GetTriangleVertex(self.hitmark,i)

local vp = self.srfc:GetVertexPosition(v)

local p = self.entity:GetPosition(true)

System:Print(vp)

System:Print(p)

end

 

 

it is the link in the index under Surface that has the reference to GetTriangleCorner on the website, at least for me. its not on any other part of the website, and it doesn't highlight, but still this should have returned a triangle not nil method

 

self.hitmark refers to a Pick Triangle

[I am missing GetTriangleVertex? [solved]]

I have an error message stating GetTriangleVertex is a nil value. does anyone know what that means? It is listed as GetTriangleCorner or GetTriangleVertex under Surface in the documentation but neither seem to work

 

I have created a "nearest Vertex" Script, based on GetEntityNeighbours.It returns the vector nearest the position stated. Here it is

 

It will be slow with high numbers of vertices

GetVertexCallbackTable = nil
function WorldGetVertexInAABBDoCallback(entity,extra)
local k = entity:GetKeyValue("mining","")
local p = entity:GetPosition(true)
if k == "true" then
local d = {}
local v = 1000
local a = 0
local b = 0
local sfc = entity:GetSurface(0)
for i = 0,sfc:CountVertices()-1 do
local u = sfc:GetVertexPosition(i)
local pos = extra - p
d[i] = pos:DistanceToPoint(u)
end
for i = 0,sfc:CountVertices()-1 do
for u = sfc:CountVertices()-1,0,-1 do
if d[i] <= d[u] then
 if v > d[i] then
 a = i
 v = d[i]
 end
end
end
end
table.insert(GetVertexCallbackTable,a)

end

end
function GetVertex(entity,position)
local result
local aabb = AABB()
local p = entity:GetPosition(true)
aabb.min = p - 5
aabb.max = p + 5
aabb:Update()
local table = GetVertexCallbackTable
GetVertexCallbackTable = {}
entity.world:ForEachEntityInAABBDo(aabb,"WorldGetVertexInAABBDoCallback",position)
result = GetVertexCallbackTable
GetVertexCallbackTable = table
return result
end

[emitter failure]

it was SetDuration, not in milliseconds

[emitter failure]

I have this emitter giving a pulse at a normalised vector of itself but it won't fire. can anyone give me advice on what is wrong with this script?

 

Thank you

 

 

local n = b:Normalize() * 4

local ect,e

if e == nil then

 

ect = 10

e = Emitter:Create(5)

e:SetPosition(n,true)

e:SetInterval(1)

e:SetDuration(5)

e:SetEmissionShape(1)

e:SetEmissionVolume(0, 0, 0)

e:ClearAlphaControlPoints()

e:ClearScaleControlPoints()

e:AddScaleControlPoint(0, 4)

e:AddScaleControlPoint(1, 6)

e:SetParticleColor(0.1, 0, 0, 1, 0)

e:SetParticleColor(0.95, 0, 0, 1, 1)

e:SetVelocity(0, 0, 0, 0) --e:SetVelocity(n.x, n.y, n.z, 0)

e:SetVelocity(0, 0, 0, 1)

e:SetLoopMode(false)

 

end

 

if e ~= nil then

ect = ect - 1

if ect == 0 then

 

e:Release()
