Nice!

October 24, 2014

Hello,

This is not a suggestion on a new feature directly. I suggest you read this paper and see if it could be of any use for Leadwerks: http://www.cse.chalmers.se/~olaolss/get_file.php?filename=papers/clustered_with_shadows.pdf

Here is a page with some slides about the paper too: http://www.cse.chalmers.se/~olaolss/main_frame.php?contents=publication&id=clustered_with_shadows

I have not read it in detail but it looks like a good optimization that could work with deferred rendering.

I hope It can be of help.

Hello,

I know that the set of tools I have to work with is Font::GetHeight, Font::GetTextWidth and Context::DrawText.

I am creating a (reusable) UI lib for my current project. I want to be able to clip text. Does anyone has some experience to share about implementing a text field in C++ using Leadwerks. What are the pitfalls etc.

Thank you in advance!

Nice finding indeed

Maybe this topic should be a sticky one.

It looks like the walls have no thickness, am I correct? Generally, those types of seams are a result of walls that are too thin. Unfortunately, the only real way to fix this problem is to make the walls thicker.

... to evolve a little bit on that, I usually stick to these dimensions mentioned by Josh here: http://www.leadwerks.com/werkspace/topic/10016-mapping-standards/

I do not know if this could be useful for you Josh but maybe it is:

I am far from an expert but I think you need the _NET_WM_STATE_FULLSCREEN hint also.

I did take a quick look for _NET_WM_STATE_FULLSCREEN in SDL2 and the interesting files to start digging in are the following:

SDL2-2.0.3\src\video\x11\SDL_x11video.c
SDL2-2.0.3\src\video\x11\SDL_x11video.h
SDL2-2.0.3\src\video\x11\SDL_x11window.c

Download https://www.libsdl.org/release/SDL2-2.0.3.zip

A trustful source for these kind of things is anything Ryan "icculus" Gordon has written.

Hello community and Leadwerks devs

Often we Leadwerks users only write something on the forum when we have problems, bugs, questions or wants a feature. There is nothing wrong with that, because the intention of the forum is to be a place for writing about you problems, bugs, questions and features we want

However, to boost our Leadwerks devs (I guess that is only Josh right now) we should also post why we think Leadwerks is the awesome sauce.

So no negative stuff in this thread ... that is what we have the rest of the forum for

Leadwerks is the awesome sauce because:

- The C++ API is very nice. It is easy to build well organised code around.

- It is ported to Linux

- OpenGL 4

- The royalty free License

- Steam integration

- Affordable Price

Been watching this a little at a time. I'd love for a language to not have headers/include guards/circular dependencies/etc, though I can't imagine how that would work.

Rust have no separate declarations or header files and Rust is a system programming language.

Josh could you please run the following on your dev box and post it here:

pkg -l | grep gtk

Then I can compare versions with my set of gtk packages.

Royaties is a good point only when you achieve and finish a complete game and be enought successfull before considering any Royalties.

If you have ever run any form of company you would know that royalties is a big thing ... so I would not downsize it to what you wrote. Royalties take a cut of your cookie. I want to keep my cookie.

September 24, 2014

I had that too after my upgrade. You need to add

dl

To "Project -> Build options -> Linker settings -> Link Libraries" on both Debug and Release.

Jon Blow - The guy behind Braid and The Witness

Good stuff, he has good points (2 hour long but very interesting):

http://www.gamasutra.com/view/news/226070/Video_Jon_Blow_on_building_a_new_programming_language_for_games.php

The video is not about a new game scripting language ... it is about creating a system programming language level language like C++ etc. that targets game development.

It should be:

self.skybox = Texture:Load("Materials/Sky/skybox_texture.tex")

There is C++ code where there should be Lua code in the code example box (and vice versa). This should be filed under "documentation bug"

Hardly "full-featured" it doesn't do eye tracking

Will Oculus and Morpheus do that. I think not

September 18, 2014

The dev kit looks better than both Oculus and Morpheus already:

https://www.kickstarter.com/projects/2091603040/totem-the-premium-full-featured-virtual-reality-he

Onboard positional tracking instead of external. Internal tracker gives you full freedom instead of being limited to moving within the external tracking FOV.
Internal focus, very good for us with glasses because we can skip the glasses when we us the Totem
No need to remove the headset every time you need to be in the real world. Totem’s integrated on-board cameras allow the user to switch seamlessly without having to take off the headset at the touch of a button.
The night vision goggle looking prototype sure looks good =)

Your tar.gz file does not appear to be valid.

I tried your texture and it worked with no problems.

What GPU do you have?

Ooo you replied when I was typing:

I have:

1. Checked the file permissions on my project. I have write and read permissons ... I allso tried chmod 777.

2. Reinstalled Leadwerks (on my vanilla ubuntu running Unity).

3. Created a brand new project after the reinstall:

Even with this new project that has no changes at all (no new code, no new resources like textures and models) I still get SIGSEGV when I try to open things like ~/Documents/Leadwerks/Projects/bughunt/Materials/Concrete/concrete_dirty_diff.tex (double clicking in the assets tab or right clicking on the asset an choosing Edit).

Thanks macklebee,

I used your script straight off. Ok, almost no changes. I changed the name to gradient.shader. I did not replace drawprimitive.shader.

I ended upp with code looking like this ... and it works perfectly:

Branch::BranchLoop::BranchLoop(Leadwerks::Context * ctx, Leadwerks::Window *win,
Leadwerks::Camera *cam)
{
...
rshader = Leadwerks::Shader::Load("Resources/Gradient/gradient.shader");
}
...
void Branch::BranchLoop::postRenderUpdate() {
Leadwerks::Shader *old = context->GetShader();
context->SetColor(1.0, 1.0, 1.0, 1.0);
rshader->SetVec4("endcolor", Leadwerks::Vec4(0.0, 0.0, 1.0, 1.0));
rshader->SetInt("horizontal", 0);
context->SetShader(rshader);
context->DrawRect(350, 350, 200, 20);
context->SetShader(old);
}

I experimented a bit and discovered that if I took care of setting all uniforms before I made my rshader the current shader I got a nice color gradient when I called DrawRect.

I have the attached the ltrace and strace logs to this one. I forgot that only certain suffixes work when attaching.

I am a bit of a GLSL noob. You are the experts so this is probably easy to answer.

I want to draw a 2D color gradient (as part of the ui) on screen. Lets say I want the gradient to be drawn at x: 100 y:100

and have a with of 200 and a height 50.

I guess I would have x, y, width and height as uniforms in my shader (I will figure out the rest of the glsl later on).

Ok now for one of the questions. Should I use SetShader on Leadwerks::Context to apply my shader? Something like this:

Leadwerks::Shader *myShader;
Leadwerks::Context *context;
...
myShader->SetInt("pos_x", 100);
myShader->SetInt("pos_x", 100);
myShader->SetInt("dim_width", 200);
myShader->SetInt("dim_height", 50);
context->SetShader(myShader);

Another question is. Should I set the shader before or after world->Render(); My guess is after.

And yes, I want to use a shader.

Thank you for all the help I can get.
