First Person by Default - AND ONLY :)

pwsi · 09-06-2017 08:22 AM

Been working with update camera to different views however want to try to run with FirstPerson cam by default and no switch option... Having trouble doing that... Would post code I've been screwing up but a little cumbersome. Anyone else have success in doing so?

Just take the first person camera from "14 - Camera Modes" tutorial and leave out the isometric and 3rd person one?

It sounds like you are secretly asking us how to program. grin

If so, please ask.

Well.. I left a project was working on for quite some time in UE4 (with some headaches in regards to engine versions) and decided the stability and overall architecture of Esenthel is better. So excuse me if I got a bit used to form based options and that sort of thing.... In this case I did try to edit 14 - Camera Modes but wasn't sure what to keep/move exactly.

No worries, just wanted to know how familiar you are with programming. smile

Here is the tutorial with all other camera modes removed:

Code:

class Player : Game.Chr

{

   bool update()

   {

      if(action)

      {

         if(Kb.b(KB_W) || Kb.b(KB_S) || Kb.b(KB_A) || Kb.b(KB_D) || Kb.b(KB_Q) || Kb.b(KB_E))actionBreak();

      }

      if(!action)

      {

         // turn & move

         input.turn.x=Kb.b(KB_Q)-Kb.b(KB_E);

         input.turn.y=Kb.b(KB_T)-Kb.b(KB_G);

         input.move.x=Kb.b(KB_D)-Kb.b(KB_A);

         input.move.z=Kb.b(KB_W)-Kb.b(KB_S);

         input.move.y=Kb.b(KB_SPACE)-Kb.b(KB_LSHIFT);

         // dodge, crouch, walk, jump

         input.dodge = Kb.bd(KB_D)-Kb.bd(KB_A);

         input.crouch= Kb.b (KB_LSHIFT);

         input.walk  = Kb.b (KB_LCTRL );

         input.jump  =(Kb.bp(KB_SPACE ) ? 3.5 : 0);

         Flt max=DegToRad(900)*Time.d();

         angle.x-=Mid(Ms.d().x*1.7, -max, max);

         angle.y+=Mid(Ms.d().y*1.7, -max, max);

      }

      return super.update();

   }

   virtual uint drawPrepare()

   {

      uint draw_mask = 0xFFFFFFFF; // set all groups enabled by default

      FlagDisable(draw_mask, IndexToFlag(DG_CHR_HEAD)); // clear head draw group flag

      SetDrawMask(draw_mask); // set draw mask

      uint modes = super.drawPrepare(); // call default drawing after setting the mask

      SetDrawMask(); // reset default mask

      return modes;

   }

}

The issue I was having was around line 114 of Camera Mode Demo and taking out the switch VIEW_FPP... As well as virtual uint drawPrepare() I see taking out bool hide_head is the way to go and adding FlagDisable... Thanks for the response!!!

pwsi · 09-06-2017 09:19 PM

Now I am asking for programming help... Basically trying to get First Person working in your Visual Event System. A couple things going on here... Was able to get first person showing up by placing the First Person code in Main ONLY. (That was first step to get it working, but interaction wasn't working and was afraid it was called to Player.cpp from other places..
So decided to place

Code:

virtual UInt drawPrepare();

   {

      uint draw_mask = 0xFFFFFFFF; // set all groups enabled by default

      FlagDisable(draw_mask, IndexToFlag(DG_CHR_HEAD)); // clear head draw group flag

      SetDrawMask(draw_mask); // set draw mask

      uint modes = super.drawPrepare(); // call default drawing after setting the mask

      SetDrawMask(); // reset default mask

      return modes;

   }

...in player.

In MAIN I changed the void UpdateCamera() to reflect required for first person camera.

NOW, what is happening I am getting an error showing character not allowed as an identifier and I think its in drawPrepare. I am at a loss.
admittedly.

For now, you can just go into the Camera class, and replace the four lines that set the camera in the update with these two:

Code:

C OrientP *head=Players[0].skel.getSlot(8"head"); // obtain player "head" skeleton slot (this was created in Object Editor)

         Cam.setPosDir(head.pos + finalOffset, head.dir, head.perp); // set camera from 'head' position, direction and perpendicular to direction

Also go into Interact, and replace the update with this:

Code:

void Interact::update()

{

   clear();

   if(Players.elms())

   {

      Player &player = Players[0];

      if(!valid)

      {   

         C OrientP *head=Players[0].skel.getSlot(8"head"); // obtain player "head" skeleton slot (this was created in Object Editor) 

         Vec dir = head.dir;

         Vec pos = head.pos + (dir * 0.5f);

         PhysHit hit;

         if(Physics.ray(pos, dir*10, &hit))

         {

            valid = true;

            obj = hit.obj;

            pos = hit.plane.pos;

            // Set the mesh to be highlighted

            highlight = true;

            // Clicked on the object

            if(Ms.bp(0))

            {

                    if(ButtonObject  *temp = CAST(ButtonObject, hit.obj)) temp.Activate();

               else if(Item          *temp = CAST(        Item, hit.obj)) temp.PickedUp();

               Ms.eat(0); // Eat the mouse operation (this mouse click does not count for anything else in the project)

            }

         }

      }

   } 

}

You don't have to bother with the drawPrepare for now.. Eventually, you will want to do it to hide the face while in FPP, but for now, it'll work fine (To use it, you have to assign body groups to your player character. My project doesn't have that set up, the tutorial does for the Warrior character).
Also, I'm preparing yet another update where you can toggle the camera between first person, third person, or looking at things with an event. So, the code I just gave you is temporary (but works fine for just first person only)
