[Leadwerks 3 FAQ - Frequently Asked Questions]

Can I export my CSG brushes?

You can save CSG brushes as a prefab but you can not export you CSG brushes as fbx, obj etc. This has been requisted though but is not confirmed to be part of the editor.

Being nit-picky here, but requested is how you spell requested Useful FAQ though

[[Linux] Model editor. Model visibility problem]

I'll hopefully be getting online later today, so will start testing this more vigorously then. Hope this gets figured out soon, I'm stuck mapping until this is sorted

[[Linux] Model editor. Model visibility problem]

Actually it reproduces in-game for me (C++ project). Strange that all the missing polys are always the same, in-game or not, however they are different for different frames of the animation. It's like the poly count sent to OpenGL is wrong or something. My mesh has multiple materials, I wonder if that is causing it.

[[Linux] Model editor. Model visibility problem]

I have this issue too, doesn't happen on the crawler for me. Will post a video soon, my Leadwerks computer is currently working offline due to me house-sitting.

 

SPEC:

NVidia GeForce 560 Ti OC

Linux Mint 16 (unsupported, I know, but since others are experiencing this problem, I don't see the need to test in ubuntu)

Can't remember the nvidia driver version, will add more info later.

[Small Entities Fall Through Terrain]

may I suggest that you make it switch off 'normal' collisions when velocity is high, in favor for checking with raycasting, and doing a custom physics for it (you can make your own drag dynamics and stuff then), then when the velocity is low, switch back to normal physics

[What are you working on :]

Is that with Release mode? My game is basically unplayable in debug mode. But is fine in Release mode.

 

For comparison:

I'm using a limited adjustable world size. Currently set to 512x512x256 for increased load time; It can be higher, but I get bored waiting everytime I debug haha. My system uses 3D chunks that are 16x16x16, with a view distance of 6x6 chunks on the horizontal plane, and 2 vertically.

I limit how many chunks can be rendered per frame, and automatically adjusts it based on the current FPS. So higher FPS = faster chunk loading, it tries to keep it around 55 FPS.

 

Pitty I can't create the models and call Update() on another thread, or can I?

[What are you working on :]

I too am fiddling around with a voxel game Haven't gotten around to adding and removing tho, but I think you can use surface->Clear(), then rebuild the surface of the mesh

 

BTW how do I upload images?

Thanks, I'll give it a try when I get home Yours looks nice, do you use Surface->Update(); or just Surface->UpdateAABB();? My Normals don't seem to turn out correctly if I only use UpdateAABB().

What kind of view distance do you run?

[What are you working on :]

Voxels!!

 

Need some help with this:

http://www.leadwerks.com/werkspace/topic/9701-best-way-of-handling-a-changing-model/

[Best way of handling a changing model]

Hey guys, I'm doing some tests for some voxel based stuff. I have a rather large 3D array that is setup at load-time, then during run-time an array of smaller 'Chunks' are created, which are basically just containers with models with a little more information such as showing if that chunk needs to be "re-modelled".

 

Now the problem is how do I go about refreshing that model. I need to replace the vertices in each Surface, is there a 'ClearSurface' function? I had a quick sqoodle through the documentation but couldn't spot one. Do I have to destroy the model and create a new one? If so, how is the best way to do that?

 

Cheers!

 

EDIT: TLDR: I already have the code to create the model -and it works perfectly, but I need to clear, and rebuild the model.

[Debugging in c++]

Welllll, they work, I can add watches to see the contents of variables, and step through code..

I don't have much c++ experience (I still have trouble with things like passing arrays of classes to a function), so I can't really say what it compares to other c++ IDEs. This is really the hardest I've ever worked with it.

 

I come from .Net/Mono, FreeBASIC, and most popular scripting languages. Oh man I'm missing c# so bad (I even tried embedding mono, but realized I'd have to learn c++ either way), please tell me this gets easier haha

[Debugging in c++]

If anyone else is having problems getting Code::Blocks to start debugging this page has the fix! http://www.unixmen.com/fix-process-terminated-status-255-codeblocks/

[Debugging in c++]

Hey guys, it's me again

 

I'm trying to get some of information out of my c++ game, it does some self-tests at startup, and I'd like it to be able to write in to a debug screen somewhere, I've tried Debug::Error(s) but nothing appears, I've also tried System::Print(s) but also nothing appears.

 

Also breakpoints don't seem to have any affect, probably because it's not running from within Code::Blocks, is there a way to run it with breakpoints?

 

 

Do I have to sort out my own debug screen or something? Thanks!

[[Linux] Losing animation after material removal]

if you want to remove the material, you can modify the default shader to be animated, I suggest calling it something like 'default+animation'.

I've done it before by copying from the Vertex shader program of an animated shader, and used the fragment shader of the default shader (of course renaming variables that were different).

[Sending objects or values to/from LUA]

I have no particular thing I want to do, my projects at the moment are basically testing what I can/can't do

I'm just going to use a Lua project I think. That way any global variables and such are easily accessible from all my code.

 

In this case, I was making a day/night cycle simulation, and needed to access the camera (to SetClearColor) from c++ and control the camera from a FreeFlyCam object written in Lua.

 

On another note: is there an "option explicit" (from VB) equivalent in Lua that forces explicit declaration of variables? I keep mis-typing my variables, and spending ages trying to debug the original cause that's not obvious at all.

[Sending objects or values to/from LUA]

Ok, that's a start. But looks like I'll have to convert my game entirely to LUA to get more control .. at-least until there's more documentation or something

[Sending objects or values to/from LUA]

Hi guys I'm trying to mix c++ with Lua. But cant figure out how to get them to interact, how would I do the following

• Send an object, such as a camera in to lua, or change the reference to a camera (that's stored in c++) from lua
  
• Send a value to/from lua
  

Thanks

[BSP multi line Slice tool and draw shapes tool]

I just need subtractive brushes (like in the unreal engine) XD. ahhh the good old days of making deathmatch/CTF maps

[Lua complete game experience]

I'm hoping someone will embed mono in 3.1 some day haha I'd do it myself, but am yet to get my test c++ project to compile :/

[Scale options for terrain]

Hi there, was wondering if we could get the option to rescale the terrain object. I'm currently feeling super limited by it.

 

I'm making a game that's mostly free-roam, and 4096x4096 maps don't work too well for me I was wondering if I could just use a 1024x1024 map scaled to 4096x4096. That way it'll look less stretched in the heightmap editor I have, and it'd be smooth to edit in Leadwerks.

 

At the moment, I'm considering the horrible option of scaling every object down to fit the terrain size :s

[Unable to navigate "perspective view"]

Hi there, I'm running Linux Mint 16, not getting the same issues as you. No idea what it could be, sorry.

[C:\Users\AppData]

type %appdata% in your address bar this will put you in the 'c:\users\<name>\AppData\Roaming\' folder, if you want local etc, just go up a level

[skydome]

hmmm, wonder if this is possible by creating a script that renders everything from a skybox camera first, then clears ONLY the depth buffer, and renders the rest of the scene from the main camera?

 

I don't know how to implement that yet, but maybe you do?

[raw file import for terrain]

ok done!

it's largely untested, I've been working extra hours the last couple of days, so if there's any bugs just post a reply here and I'll get on it as soon as I can. Or if you fix it yourself in the source, please let me know, so I can apply it! thanks!

 

I'll throw a copy in the tools section of my site too

 

on windows you can just drag the file on to the exe and it'll pop a raw file out right next to the image (or an image next to the raw). On linux just use the command line mono rawconv.exe [inputfile]

 

forgot to mention you need mono/.Net 2.0

 

Oh yeah, if it detects Cairo (included with mono) it'll use that to load the image file instead of System.Drawing, since I was having problems with System.Drawing on linux. But since most windows systems don't have Cairo, I've made it detect the assembly and load it at runtime, so windows users don't need to care.

[raw file import for terrain]

Hey, everyone I've almost finished an image (png, bmp, jpg) to raw (and back) file converter. It currently works on Windows, but is reading a blank image on linux, once I fix this bug, I'll give the source, and binaries.

[raw file import for terrain]

ok, I'll look in to it, if I come up with something I'll share
