['Buffer' has no current documentation]

I've gotten render to texture working using this code http://leadwerks.wikidot.com/wiki:render-to-texture-security-cam but the Buffer functions are nowhere to be found in the current documentation. Unless I missed it, in which case please point it out Buffer isn't even highlighted in the script editor.

 

I wasn't sure whether to post this in Bug Reports as it's not to do with the program itself...

[Requested Features and Improvements]

This is exactly what it does when an error occurs. The call stack is shown in the Lua debugger.

 

Does it have to be run in debug mode for that?

 

EDIT: I just tried it and I understand now.

[Pivot point selection - rotatting groups of object primitives]

I'm unsure if you actually can change the 'pivot point' of an object, what I do is create a Pivot entity and then drag parent my objects to that. You can then rotate that Pivot and all it's children will rotate correctly.

[How do you get the current date?]

I get it now, it only has an effect on projects being launched from the editor. os is still available when the .exe is ran manually. Thanks again.

[How do you get the current date?]

For os or io commands in lua, you need lua sandbox disabled. Go to the Editor's Tools-->Options and uncheck the Sandbox Lua option.

 

Thanks.

 

Is there any reason I would want to keep it on?

[Requested Features and Improvements]

One thing I would like to see is a better stack trace for Lua errors.

 

So when there is an error it doesn't just tell say which file/function, but also shows the chain of function calls leading up to that.

["Level geometry" folder in scene]

Definitely agree. I started moving them ino/parenting to a pivot so they were all grouped, but then any new ones still have to be moved again.

[Math:DeltaAngle does not exist (not exposed to Lua?)]

I was trying to use Math:DeltaAngle but it doesn't seem to exist. I guess it is a C++ function that hasn't been exposed to Lua.

 

 

I'm using this as a temporary fix and it seems to do the job:

function Math:DeltaAngle(a,B)
local d = b-a
d = d + (( (d>180) and -360 ) or ( (d<-180) and 360) or 0)
return d
end

[How do you get the current date?]

I tried to do:

local DateRan = os.date("%Y.%m.%d.%H.%M.%S")

but got

attempt to index global 'os' (a nil value)

 

I did a search and couldn't see an obvious alternative.

[SetElasticity and SetSoftness functions? (Lua)]

Yep, I'm already going to be doing those things in different situations so it's not really a simple option. Gravity is disabled on the world and the ball applies a force to itself to simulate gravity so I can change the direction of gravity (not sure if you can change the gravity direction for the entire world?). I'll try and work around it for now.

[SetElasticity and SetSoftness functions? (Lua)]

Although doing it manually doesn't give the ability to have less than normal bounce.

 

EDIT: Sorry for double post. I'm used to posts auto-merging together on another forum.

[SetElasticity and SetSoftness functions? (Lua)]

It seems that those are older functions from LE 2. At the moment I do not believe such functions exist (at least for lua). I had a similar issue so I made a little script for my ball to make it bounce. It looked like this -

 

function Script:Collision(entity, position, normal, speed)

self.entity:AddForce(0,.25*speed,0) -- Add Global force to make the ball bounce upwards.

self.entity:AddForce(0,.25*speed,0,false) -- Add Local force to make the ball have a random bounce

end

 

Thanks, I thought that might be the case. I just didn't want to have to do it myself.

[SetElasticity and SetSoftness functions? (Lua)]

I have a model of a sphere with a collision mesh imported into Leadwerks and I wanted to control how 'bouncy' it was. Did a google search and came across the functions SetElasticity and SetSoftness (seems like they were called SetBodyElasticity and SetBodySoftness in older versions).

 

The current docs don't mention these functions, or at least not on Entity, and when I try to call them they obviously don't exist. Does anyone know if they've been renamed, not available to Lua, removed for some reason?

 

Just a few things I found:

http://www.leadwerks.com/werkspace/topic/2546-balls/ (This has a Lua script that calls SetElasticity which makes me think it did exist at some point)

http://www.leadwerks.com/werkspace/page/Documentation/le2/_/command-reference/bodies/setbodyelasticity-r58 (Old docs)

http://www.leadwerks.com/werkspace/topic/4683-problem-with-collision-callback/ (C++ but calls SetElasticity)

[No Lerp function?]

I just tried using Math:Lerp for the first time and get the error:

attempt to call method 'Lerp' (a nil value)

This is how I am calling it, I have also tried Math.Lerp and just Lerp, they don't work either.

local R = Math:Lerp(self.DayAmbient.x,self.NightAmbient.x,Intense)

 

As as a test I did I

for k,v in pairs(Math) do print(k,v) end

and I couldn't see Lerp anywhere in the output

 

I understand how Lerp works and can write the function myself to get around this, I just didn't know if the documentation is wrong or I am having some kind of bug or what.
