Project InterDimension Drive MFD

[gattispilot]

This is my first MFD also. Thought I would start a new thread for it. It is a MFD to allow a vessel to travel from one location to another location at a high rate of time/speed. Of course it is Science fiction. But it is based off ideas from several TV shows.
I supposed the idea is to use worm holes. There are a couple of MFD's addon's that do Warp or Jump drive. BUT for traveling from one location to another on the same planet. They don't work. I understand why. The curve of the planet gets in the way.

Thanks to Face and meson800 I was able to make a SIMPLE babystep version.

Basically you enters a target vessel and it places your ship at the selected target location.

What I want and I am asking help is to be able to do the same but be able to choose a base rather than a vessel

2 be able to calculate the distance between the selected base and your vessel.

void IDDRIVE::MOVEVESSEL(void)
{
    OBJHANDLE targetHandle = oapiGetObjectByName(targetName);  // gets the handle of target
    if (targetHandle != NULL) //checks to make sure we have a valid vessel
    {
        VESSEL *v = oapiGetVesselInterface(targetHandle);  //gets interface of target


        VESSELSTATUS2 status;
        status.flag = 0;
        status.version = 2;

        v->GetStatusEx(&status);




        VESSEL *v2 = oapiGetFocusInterface();

        v2->DefSetStateEx(&status);
    }
}

I have access to RWarp code which allows one to select the base.

bool cbSelectPlanet(void *id, char *str, void *usrdata)
{
 
     
    instance[gmfdFocus].PlanetRef=oapiGetGbodyByName(str);
    if(instance[gmfdFocus].PlanetRef!=0)
    {
        oapiOpenInputBox("Select Base", cbSelectBase, 0, 20, 0);
    }
    return true;
}
 
bool cbSelectBase(void *id, char *str, void *usrdata)
{
     
 
    instance[gmfdFocus].BaseRef=oapiGetBaseByName(instance[gmfdFocus].PlanetRef, str);
    return true;
}

So here you open and input box and enter the planet and then base. I understand that. But it is the instance[gmfdFocus], don't get.

So what is INSTANCE?
in my cpp I have

#define INSTANCES       30

 

[orb]

Is `INSTANCES` macro defined before you declare the "Global Variables"?

Was `INSTANCE` type defined earlier, maybe in another header file?

Are you including the header files with your type definitions in correct order in the code before you use them?

 

[gattispilot]

Thanks

Is `INSTANCES` macro defined before you declare the "Global Variables"?

Not sure what you mean?

Are you including the header files with your type definitions in correct order in the code before you use them?

Not sure what you mean by correct order?

What I can find is the lower case "instance"

 

[orb]

Not sure what you mean by correct order?

INSTANCES macro and INSTANCE type must be defined before you declare the variable:

extern INSTANCE instance[INSTANCES];

INSTANCE instance[INSTANCES];

What I can find is the lower case "instance"

It's in Global.cpp, as you already listed.

Progress, yes!!!

If I understand this this set all then instance{index} to your assigned values.

    //Configure
    for(int index=0; index<INSTANCES; index++)
    {
        instance[index].mode=mSTOP;
        instance[index].velocity=0;
        instance[index].vesselHandle=0;
        instance[index].stop=false;
        instance[index].stopDistance=1000000.0;
        instance[index].maxWarp=0.9999;
        instance[index].PlanetRef=0;
        instance[index].BaseRef=0;
        instance[index].gamma=1.0;
        instance[index].fval=0;
        instance[index].rmtId=-1;
        instance[index].mfdMode=mRWARP;
        instance[index].rvelSet=false;
        instance[index].matchSpeed=true;
        notePtr[index]=-1;
 
 
    }

So instance[index].PlanetRef=0;, right?

I am not able to get the input box to open.
I think it is because of the first if statement if if(instance[mfdFocus].PlanetRef!=0)
So if if(instance[mfdFocus].PlanetRef is not equal to zero then proceed., right.

But it is set to zero.

if(instance[mfdFocus].PlanetRef!=0)
                {
                    if(oapiGetObjectType(instance[mfdFocus].PlanetRef)==OBJTP_PLANET)
                    {
                        oapiOpenInputBox("Select Base", cbSelectBase, 0, 20, (void *)this);
                    }
                }
                break;

Ok. trying to get it to display my input

I can get it to display but I want it to display even with the horizon and not at an angle

Ok I can get the data to display. But it is at an angle. Even the Display Area from the template is off.

Also why yellow? I looked at the SDK Shouldn't 00FFFF be aqua?

bool IDDRIVE::Update(oapi::Sketchpad *skp)
{

	char Buffer[255];
	char Buffer2[255];
	Title(skp, "IDDRIVE");
	// Draws the MFD title
	
	
	skp->SetFont(font);
	skp->SetTextAlign(oapi::Sketchpad::CENTER, oapi::Sketchpad::BASELINE);
	skp->SetTextColor(0x00FFFF);
	skp->Text(W / 2, H / 2, "Display area", 12);
	skp->Rectangle(W / 4, H / 4, (3 * W) / 4, (3 * H) / 4);

	sprintf(Buffer, "ID:%d", mfdFocus);
	skp->Text(20, 50, Buffer, (int)strlen(Buffer));

        CurrentLine = 0;
	

sprintf(Buffer, "%s", "TARGET    BASE");
skp->Text(60, 100, Buffer, (int)strlen(Buffer));

 

[gattispilot]

Seems like I am on my own for this:

So how can one just move their ship to a selected BASE location. I can do that with a vessel.

---------- Post added at 09:37 PM ---------- Previous post was at 07:18 AM ----------

Trying something different

	char cbuf[256];
	if (targetName != NULL) //checks to make sure we have a valid vessel
	{

		OBJHANDLE hBase = oapiGetBaseByName(targetName, cbuf);
		oapiGetBaseEquPos(hBase, &lng, &lat);
	}

How can I read oapiGetBaseEquPos(hBase, &lng, &lat);s?

Is it possible to move a vessel to those coordinates.

But I can't go past it.

 

[BrianJ]

Hello,

Also why yellow? I looked at the SDK Shouldn't 00FFFF be aqua?

IIRC these values are not RGB (red, Green, Blue) - they are BBGGRR.
Try FFFF00.


As to why the text is at an angle, my first guess is it might be something to do with this line:

oapi::Sketchpad::BASELINE

What happens if you remove it?

    char cbuf[256];
    if (targetName != NULL) //checks to make sure we have a valid vessel
    {

        OBJHANDLE hBase = oapiGetBaseByName(targetName, cbuf);
        oapiGetBaseEquPos(hBase, &lng, &lat);
    }

How can I read oapiGetBaseEquPos(hBase, &lng, &lat);s?

Like this:

    char cbuf[256];
[COLOR=Red]double base_long = 0;
double base_lat = 0;[/COLOR]
    if (targetName != NULL) //checks to make sure we have a valid vessel
    {

        OBJHANDLE hBase = oapiGetBaseByName(targetName, cbuf);
        oapiGetBaseEquPos(hBase, [COLOR=Red]&base_long, &base_lat[/COLOR]);
    }

Good luck!

 

[gattispilot]

on the angled display No change when I comment this line out:

skp->SetTextAlign(oapi::Sketchpad::CENTER oapi::Sketchpad::BASELINE);

Success on the color change.

I am going to try to add this function into a vessel and then convert to a mfd.

How did you define and create the oapi::Font* font? orientation is the final parameter in "oapi:apiCreateFont()". (See: 7.51.1.2 in the API_Reference.pdf, page 134)

 

[gattispilot]

I believe just like the MFD template has it:

// Constructor
MFDTemplate::MFDTemplate (DWORD w, DWORD h, VESSEL *vessel)
: MFD2 (w, h, vessel)
{
    font = oapiCreateFont (w/20, true, "Arial", FONT_NORMAL, 450);
    // Add MFD initialisation here
}

 

[Urwumpe]

I believe just like the MFD template has it:

// Constructor
MFDTemplate::MFDTemplate (DWORD w, DWORD h, VESSEL *vessel)
: MFD2 (w, h, vessel)
{
    font = oapiCreateFont (w/20, true, "Arial", FONT_NORMAL, 450);
    // Add MFD initialisation here
}

The number 450 in that function call means 450 * 1/10° = 45° angle of orientation of the text.

 

[gattispilot]

Ok back to this. Going to try something. Place a beacon vessel where you want to go. And select the vessel you want to go to.

So how to get distance of my vessel to the selected vessel?

void IDDRIVE4::MOVEVESSEL(void)
{

	VECTOR3 aphpos, aphdir, aphrot, gaph;
	VECTOR3 shippos, shipdir, shiprot, gpship;


	OBJHANDLE targetHandle = oapiGetObjectByName(targetName);  // gets the handle of target
	if (targetHandle != NULL) //checks to make sure we have a valid vessel
	{
		VESSEL *v = oapiGetVesselInterface(targetHandle);  //gets interface of target

		//v->GetStatusEx(&targethandle);  //get status of target

		VESSELSTATUS2 status;
		status.flag = 0;
		status.version = 2;

		v->GetStatusEx(&status);
		//
		
		oapiGetGlobalPos(targetHandle, &gpship); // get global postion of ship and put into gpship
			//

		//VESSEL *v = oapiGetVesselInterface(targetHandle);



			VESSEL *v2 = oapiGetFocusInterface();

			v2->DefSetStateEx(&status);
		}
	
}

 

[gattispilot]

I can select a vessel. We are going to have a beacon vessel that one places via scenario editor at the location they want to be. Open the mfd and select the target and then jump.

But We want a 2 things. this is where I need the help. 1. to calculate the distance between my vessel and the vessel selected. An input of a speed. and then based off the distance and the speed the vessel arrives.
