[Packing scripts folder]

Hello Soamp, i'm investigating this too, i wasn't able to package the scripts folder.

 

I have a Data folder with all the models, maps, etc and this works like a charm.

 

I'm unsure if you can do this without a modification.

 

This is why i prefer to code most of the important things in c++.

 

EDIT: What you can do in the worst case is put scripts in the data folder, for an instance i have a specific script inside the model folder, so basically what i have in the scripts folder is all generic Leadwerks stuff.

[Skybox in C++?]

I had the 4 LUA lines commented, now i got it workiong, since most scripts were working i didn't cared to check that until now.

Thanks for your response guys.

 

Edit:This lines were giving me problems with physics in general, vehicle related mostly, there was a script that was messing up my c++ code, thats why i had this lines commented, now i at least found the real problem, and got all working.

[Skybox in C++?]

For the C++ code when using the atmosphere object script, you need to make sure you are passing the framework to the lua state since the script is using the 'fw' framework variable:

 

The scripts are loading OK, even the Atmosphere object of the Scene is loading, i can check that in the log, i already have that lines of code to setup script, most scripts do their work, except for the skybox.

 

I will check setting the background but im a bit lost on what im missing to be honest.

[Skybox in C++?]

I have a sbx which haves a skybox that works on the editor, on my c++ code the sky is totally black.

 

I checked the log and the enviroment object is loading OK.

 

Also i tried this:

//Set SkyBox

SetSkybox(LoadMaterial("abstract::FullskiesBlueClear0016_2_L.mat"));

 

It results on the Shader of objects reflecting the Sky, but the sky i still black.

 

Im using:

TFramework fw=CreateFramework();

TEntity scene=LoadScene("..");

Loop

RenderFramework();

UpdateFramework();

Etc..

 

Maybe im missing something to initalize the enviroment on the Framework.

 

Any idea?

[Convert object to integer and back]

I think if:

Object* o;

int pointer = *(int*)o;

 

then

Object* o= (Object*)pointer;

 

Gotta check this code later.

[Reading Lua Class Properties from C++]

Thanks for the responses guys, i got it working.

 

I just checked there was a sample in the viper vehicle lua.

object.model:SetKey("collisiontype",COLLISION_PROP)
object.model:SetKey("mass",1.0)

 

C++ Code:

GetEntityKey(model,"mass");

[Reading Lua Class Properties from C++]

If you store it as an entity key..

 

How do you store an Entity Key in lua?

[Reading Lua Class Properties from C++]

Is there a way to create a variable or property in a class in LUA and access it from C++?

 

For an instance there switch.lua have a Reset time property created in the Property Dialog, and then in the main function you have a resettime variable. How would i access this property/variable from c++?

 

Thanks a lot in advance.

[Traffic light "switch" model in Editor]

Any idea on how to generate a simple Traffic Light, with Green, Yellow and Red timed via scripts?

 

I was trying to figure out how to do this using the switch model .frag and .lua.

[Vehicle Brake and Speed?]

Yes you are right, this works too:

 

GetBodyVelocity(chassis,0)

[Vehicle Brake and Speed?]

I would use a brake force, and just keep applying it until it stops. To keep it from going negative, you could do multiply the vehicle's velocity on it's own z axis by some number between 0 and -1, and that will cause it to gradually slow and stop.

 

Thanks for your Repply, i don't know where to get the velocity Vector, do you have an idea on how will this be?

 

I Tried doing something like this but it crashes inside GetBodyVelocity, either using the Chassis object or the vehicle object.

appliedvelocity = (0.2 * GetBodyVelocity(veh,1).Z)*(-1);

 

Finally CalcBodyVelocity worked with this, idk why GetBodyVelocity Crashes.

 

 

Edit: Btw checking the vehicle script i found this code that is used for the decals:

						speed = math.abs(self.model:GetVelocity(0).z)
					speed = (speed - 4) / 120.0
					speed = Clamp( speed, 0, 1 ) * 0.05

I will try to convert this to C++ to use to calculate speed.

[HideEntity Won't Work]

If i use that code my project will close without giving an error. Release or Debug the same.

[HideEntity Won't Work]

Why this code won't hide my entity?

 

      TModel test=LoadModel("abstract::model.gmf");

      ....

pivot=FindChild(test,"block");
if (pivot)
{
	HideEntity(pivot);
}
else
{
	MessageBoxA(0,"block not found.","Error",0);
}

 

All names are OK since pivot is being found OK.

 

Any idea?

 

Edit: Block is a mesh inside the model, and i have no way to scale it or hide it. Tried both.

[Vehicle Brake and Speed?]

Hello,

 

Since i can't use Joystick for a Driving LUA demo, i made a c++ code that have a running vehicle based on few posts i saw and a rewrite of the original LUA i had.

 

Im applying Torque to the vehicle this way:

 

               TVehicle veh=CreateVehicle(chassis);
               .....

               TMesh tire[4];
               .....

               // Torque
	AddTireTorque(veh, 0, -1);
               if (KeyDown(KEY_UP))
			{
				if (!TireIsAirborne(tire[0])) AddTireTorque(veh, -24, 0);
				if (!TireIsAirborne(tire[1])) AddTireTorque(veh, -24, 1);
			}
	if (KeyDown(KEY_DOWN))
			{
				if (!TireIsAirborne(tire[0])) AddTireTorque(veh, +24, 0);
				if (!TireIsAirborne(tire[1])) AddTireTorque(veh, +24, 1);
			}

 

I can't seem to find a way to check Tire actual torque to be able apply negative Torque until vehicle is stopped.

I'm applying torque only to wheels 0 and 1 becouse i want a front-wheel drive vehicle.

 

My idea was to make something like this (Anyway applying 0 torque will do nothing, but if apply negative it will go backwards after stopped):

 

       // BRAKE
               if (KeyDown(KEY_SPACE))
			{
				if (!TireIsAirborne(tire[0])) AddTireTorque(veh, 0, 0);
				if (!TireIsAirborne(tire[1])) AddTireTorque(veh, 0, 1);
			}

Also Is there a way to calculate some kind of speed with raycastvehicle?

 

Anybody implemented some kind of Engine to do gears and stuff?

 

Thanks a lot in advance

[How to? Run LUA from your own C++ Exe]

Yeah i think ZioRed answered this, anyway, i have a working LUA for a driving example code, and i have an exe that have joystick implemented, and i cant put em together to work.

Is something simple, but working with leadwerks seems to be far from simple.

 

What i need is an engine.exe with joystick implemented, my other option is what im finishing now, recoding all my LUA script in c++ becouse im not getting support.

[How to? Run LUA from your own C++ Exe]

Mmm..

 

What about commented functions like LoadScript, RunScript, etc?

 

I have Setup LUA OK, but idk how to run a script in my code

 

       TFramework fw = CreateFramework();
       SetGlobalObject("fw",fw);
       BP lua = GetLuaState();
       lua_pushobject(lua,fw);
       lua_setglobal(lua,"fw");
       lua_pop(lua,1);

[How to? Run LUA from your own C++ Exe]

Does anybody remeber how to do this?

[How to? Run LUA from your own C++ Exe]

I asked this before, but all my posts are deleted!!!!

 

What were the lines to initialize lua scripts objects from c++, and to run for an instance FPSController.lua.

 

Thanks a lot in advance.
