[Mouse wheel question]

You have to check the mouse position Z component

 

class SomeClass
{
float _lastMZ;
...

void Init()
{
 _lastMZ = Window::GetCurrent()->GetMousePosition().z;
}

void UpdateWorld()
{
 auto mz = Window::GetCurrent()->GetMousePosition().z;
 if ( mz != _lastMZ )
 {
		 // mouse wheel moved
		 // distance is mz-_lastMZ
		 _lastMZ = mz;
 }
}
};

[[Solved] Fog in C++?]

The camera is a camera created in the editor and I'm 100% sure that the loaded entity is that camera as I use it my FPS player code later on

 

[Official supported Fog]

I can understand that all kinds of special effects should be user supplied. However fog is such a basic need. All engines I have tested have fog as that is the normal way to minimize the camera range. Well it's up to Josh to decide. Fog in my view is not an effect. It's a basic feature.

[Official supported Fog]

Its quite surprising that Leadwerks doesn't have official supported Fog as thats more or less needed in most programs. In some less and in some more. So please Josh! Come on - give us some fog.

[[Solved] Fog in C++?]

Hi

 

What's needed to get the Fog shader included in Shadmar's PP-shader pack working in C++.

 

I thought this was the only thing to do but the result is no fog at all. Adding the fog to the editor works and gives a nice fog, but only in the editor

 

auto cam = reinterpret_cast<Camera*>(lb.getEntity("cam")); // this is my camera
cam->AddPostEffect("Shaders/PostEffects/02_pp_fog_by_klepto.lua");
cam->SetKeyValue("fog_fogrange", "0,20");
cam->SetKeyValue("fog_fogcolor", "0.57,0.53,0.55,1.0");
cam->SetKeyValue("fog_fogangle", "5,21");
cam->SetKeyValue("fog_fogislocal", "0");

 

In editor

 

In C++ program

[Window::SetMousePosition does not set MouseWheel value]

As you can see from the code example below SetMousePosition ignores the Z-value

 

auto win = Window::GetCurrent();
auto mp = win->GetMousePosition(); // mp = { x=1000.00000 y=478.000000 z=7.0000000 }

win->SetMousePosition(11,22,33);
mp = win->GetMousePosition(); // mp {x=11.0000000 y=22.0000000 z=7.00000000 }

[Swedish characters]

As this now has gone wild I can learn you two Swedish words that are really really easy

 

Island = ö

Small river = å

[Swedish characters]

I will be honest: I fully expected to see 3d models of Swedish people when I clicked on this topic. Really wondered how you would have captured the essence of a swedish person.

Hahaha.. sorry for that

 

Here is a fully normal Swede ... (me?)

 

[Swedish characters]

I've added a new Font::Load() command that will accept any string of characters as the glyphs to pull from the font. However, I do not exactly know how this will work. It's all kind of strange to me, being a native English speaker everything else seems like some weird exception.

Anything that can be tested?

[Swedish characters]

Okay. So at the moment its not possible then (my font has the Swedish åäöÅÄÖ).

 

å (0xe5)

ä (0xe4)

ö (0xf6)

Å (0xc5)

Ä (0xc4)

Ö (0xd6)

 

 

Thanks for the answer

[Swedish characters]

My code supports the game in different languages (actually English and Swedish for now, but its quite easy to add more languages). Switching language works just fine. However Ascii-characters above 0x7F are not rendered correctly or not at all. Is the any workaround or fix for this (C++)?

 

Question for Josh? Will Leadwerks be able to deal with extended character sets in the future?

Totally off topic. What's that music?

[Need help with a simple code]

end

end

I woulf strongly recommend you to learn LUA scripting. Start of easy, check the tutorials and go in small steps. You won't regret the time spent.

[What Does This Mean?]

Hard to tell what the problem is without having the project, could be more ore less anything.

[Accessing objects in editor from C++ code]

To use C++ you should open Projects\Windows\<your projectname>.sln in Visual Studio and compile.

If you don't want Main.Lua to be executed you can go for a more clean approach and replace main.cpp

with something like this

 

#include "Leadwerks.h"
#include <sstream>

using namespace Leadwerks;

int main(int argc, const char *argv[])
{
   // Initialize Steamworks (optional)
   // Steamworks::Initialize();

   // Create the app window
   Window* window = Window::Create("My Game", 0, 0, 1024, 768, Window::Titlebar);

   // and some context to draw on
   Context* context = Context::Create(window, 0);
   if (context == nullptr)
   {
       return 1;
   }

   // The world containg all objects
   World* world = World::Create();

   // Load a map into the world
   if (!Map::Load( "Maps/start.map" )
   {
       return 2;
   }

   // Loop until window is closed or user presses ESCAPE
   bool showstats = false;
   while (!window->KeyDown(Key::Escape) && !window->Closed())
   {
       Time::Update();
       world->Update();
       world->Render();

       context->SetBlendMode(Blend::Alpha);
       showstats = window->KeyHit(Key::F11) ? !showstats : showstats;
       if (showstats)
       {
           ostringstream fps;
           fps << "FPS: " << Math::Round(Time::UPS());
           context->SetColor(1, 0, 0, 1);
           context->DrawText("Debug Mode", 2, 2);
           context->SetColor(1, 1, 1, 1);
           context->DrawText(fps.str(), 2, 2);
           context->DrawStats(2, 22);
           context->SetBlendMode(Blend::Solid);
       }

       context->Sync(true);
   }

   return 0;
}
