Player mesh disappears after a while.

Hey there.

Another problem I came across:

I am working on an endless runner style game right now.
After a while, the player mesh disappears.

There is still the shadow (which however disappears 100 units later as well)
and the actor is still there,
because I still have collision and the camera is following the player.

Why is that? I am a bit lost here.

could you show your drawing function ?

I got the mesh fixed already, thanks.
I needed to iterate over the object in the render function --> case RM_PREPARE.

However, the shadow still disappears after pos.z > 200...

the code is this:

Code:

UInt RBall::drawPrepare()

{

   actor.draw();

   if(mesh) mesh->draw(actor.matrix());

   return 1;

}

void RBall::drawShadow()

{

   if(mesh) mesh->drawShadow(actor.matrix());

}

EDIT: Well, and after pos.z > 256 I lose control over the player.

It has an actor.velocity() function running in update,
that stops working after pos.z ~256, and I have a logging text running
for actor.pos(), that stops updating as well...

So looks like there is another thing going on which I don't know anything about...

objects outside of world active range are automatically unloaded

Ok, I understand. But why does the shadow disappears at pos.z 200
and the Mesh is still there before I lose complete control at pos.z > 256?
That's what I can't quite understand. And I don't know how to fix that.

Also:

Game.WorldManager.update(C Vec &position) is set to the player.pos().

shouldn't that center the active area around the player then?

EDIT:
I also tried now to use a pointlight that moves with the player.
Here, the shadow also disappears, even a bit earlier than with the directional light.
Why??

it should, if you use the WORLD_MODE as WORLD_STREAM.

could it be some weird frustrum ?

KrysleQuinsen · 08-28-2021 04:41 AM

IIRC, shadow/light stopped drawing due to camera and character exceeding the D.viewRange();
While Character got cached and disappear due to exceeding Game::World.activeRange();

You may want to try WORLD_FULL instead of WORLD_STREAM.
Game::World.mode(Game::WORLD_FULL );

Also, try to update WorldManager to Camera instead of a player position and move the camera along the player and see if it is improved.
Game::World.update(Cam.at); in the Game Update.

Thanks guys, I will check after the weekend and report back.

However, I think that I tried this already, not sure though:

Quote:Also, try to update WorldManager to Camera instead of a player position and move the camera along the player and see if it is improved.
Game::World.update(Cam.at); in the Game Update.

This here:

Code:

Game::World.mode(Game::WORLD_FULL );

I tried 100% and it did some crazy stuff, can't remember what exactly,
but I switched immediately back to STREAM.

The camera is a follow cam (set to player[0].pos().z - 5 or something like that) anyways, because Endless Runner.

But I'll let you know how it goes when I can check.
Thanks again.

I wouldn't recommend using the WORLD_FULL mode unless you have a fixed size level you want to completely load into memory whilst disabling streaming terrain and any automatic loading/unloading of objects. Endless runner screams STREAM to me.

Fluxor · 08-28-2021 06:17 PM

Yeah I've noticed. Like I said above , I tried it and switched back to WORLD_STREAM right away because this didn't work at all...
