[Rotating a bone]

This is a really hard thing to do and unfortunately it only ever works with upright bone models. 
I made spider legs but modeled them like this
place bone, do not rotate scale etc
extrude it to the top
Then it is possible to rotate them, but also only tested with setrotation()

[Read a JSON file into a Lua string / table]

Personally I would use leadwerks stream and make my own parser and file system depending on what I need
for example
names.data
foo

bar
then loop trough all the lines and read all the data into an array

[glu.h missing]

I also had trouble in the beginning with the default project settings

[Slider not scrolling with mousedrag when window is too small]

I had this happen so often to me over years on random applications and feels like this has bugging me ever since. 

[Black Window after player Z position > 2000]

It seems to be very small at 4000 aswell.
In this scene I put the size to 4000 in the editor and did the same thing from before but the player still disappeared.
This is a major issue to the game I want to develop, and even still this should not be the limit to this engine.

[Find a vertex from global position]

this is enough for collision but to maek your actual wayve more interesting you could add smaller noises at higher frequency than the big wave.

[Find a vertex from global position]

I see.
You don't need a displacement map. This can easily be calculated
this is basically a cos function in the range of [0, 8*pi]
pixel(x,y) = cos((y/height)*3.1415926*8)

Just to give you a headstart.
To get the color information you would use the function from above like this disp = (pixel(x,y)*0.5+1)/255
because cos goes from -1 to 1 and if we add one it goes from 0 to 2, then multiply by 0.5 to get from 0 to 1 and divide by 255 to get the color intensity.
 

[Find a vertex from global position]

The shader still calculates the height of the wave trough a function. It must contain sin / cos.
If you copy that function to lua with the same parameters, it will have mathematically the same result. Which parameters would need to be converted from leadwerks global space to whatever space the shader operates.

[Find a vertex from global position]

You would need to get the surface of the model. 
Not tested here I will give you a tip:
 

local model = Model:Load("Models/Grass/grass01.mdl")  
local surface = model:GetSurface(0)
local smallest = nil
for v=0,surface:CountVertices()-1 do
    local position = surface:GetVertexPosition(v)
  	--multiply by scale (you mentioned 1500)
  	local vertDistance = self.entity:GetDistance(model:GetPosition()+(surface:GetVertexPosition(v)* 1500))
	if smallest == nil or vertDistance < currDistance then
    	currDistance = vertDistance
		smallest = v
    end
end
local posOfNearestVert = model:GetPosition()+(surface:GetVertexPosition(smallest)* 1500)

This probably wont work on the first try, but is an example on how to approach this.
Also you cannot directly get the vertex, but the position as presented

[Decals disappearing from view.]

You might use 
https://www.leadwerks.com/learn?page=API-Reference_Object_Entity_SetOcclusionCullingMode
SetOcclusionCullingMode to true or false and look at the results.
For this you need to add a script to each decal, or make a "decal handler" that sets this for every decal entity.

Update, in the video even an empty project with the fps player and high movement speed, I can get to the "edge".
In this case it seems to be at z +  ~1503 and 1513
How come this happens ?

I have newest gfx drivers ..
And some more files:

[Black Window after player Z position > 2000]

I have not come closer to the issue, but it might be that I am setting the camera position by SetPosition and the player does not "move", I also place him with SetPosition. Maybe some kind of vector doesnt update the position ?

Just now, Josh said:

Floating point errors will occur as you get further from the origin. 2000 units seems a bit low though.

That's what I thought, too 

[Black Window after player Z position > 2000]

When I move the player a long distance from the world origin,
firstly the shadows disappear and after Z > 2000 the screen is totally black
First it is all normal:

then shadows disappear


and then (z> 2000) only things from postrender get drawn on the screen.

Position x:7.6799964904785 y:1.4799995422363 z:1264.5567626953 -- round about here shadows disappear (+-50)
Position x:7.6799974441528 y:1.4799995422363 z:2033.2707519531 -- here black screen (+-50)

[Window::Titlebar works but not Window::FullScreen]

Hello
I have a problem creating a window in c++, when I use this 
 

window = Leadwerks::Window::Create("Game Test",0,0,1280,720, Window::FullScreen);
context = Context::Create(window);

the window will appear correctly but as soon as I try to make it any resolution higher than 1920 1080 the window will not be created.

Is this some kind of surprise windows setting that causes this or is this a leadwerks bug?

[Cant think of a name]

make a new script

Script.first = nil --entity
Script.second = nil --entity

function Script:Start()

if self.second == nil then System:Print(">> second is nil") end 

end

now drag two random things in each slot of the Script tab and run the game, nothing will happen.
then click on the red x of "first" so it will disappear.
Now for some reason, second will be nil when you run the game again.
I don't know if it has some more details for reproduction but I think this should be enough.
 

[Pass c++ camera to lua player script]

Have just gone "around" this issue like this
 

Quote

world:GetCurrent():ForEachEntityInAABBDo(self.entity:GetAABB(),"Callback",v) 

 

and for some reason the camera was always in the aabb so i just checked if the entity in the parameter of callback was the camera

[Pass c++ camera to lua player script]

How do I handle the camera creation in c++ ?
I create a camera in c++ and it works fine but the Camera has no GetCurrent() so how do I pass it down to the player script ?
Basically what is the equivalent of entity.script.camera in cpp ?

I need the camera in both c++ and lua.

[What's next for UAK?]

new script editor/better direct support for VS code
better shader workflow(getting lots of engine side bugs while working with shaders)
hair (alpha like leaves.shader but animated), outline shader for selecting things
terrain heightmap generator (from 1..n noise funcitons with custom arguments)
 

[Outline shader]

Any recent version for a material outline shader available ?
Thanks in advance.
