how to avoid flickering for moving objects?

[PoussinJoyeux]

Hello,

 

I'm back to Leadwerks after a long while and starting to play again with it and C++.

 

I've done a very basic code which moves a door (why not ).

 

#include "App.h"

 

using namespace Leadwerks;

 

App::App() : window(NULL), context(NULL), world(NULL), camera(NULL) {}

 

App::~App() { delete world; delete window; }

 

Entity* EntityDoor;

float pos_z;

 

bool App::Start()

{

window = Window::Create();

context = Context::Create(window);

world = World::Create();

 

EntityDoor = Prefab::Load("Prefabs/Doors/gatevertical_door.pfb");

pos_z = 0;

 

//Load a map

return Map::Load("Maps/start.map");

}

 

bool App::Loop()

{

if (window->Closed() || window->KeyDown(Key::Escape)) return false;

 

Time::Update();

 

pos_z = pos_z + 0.005f;

EntityDoor->SetPosition(10 , 10, pos_z);

 

world->Update();

world->Render();

context->Sync();

 

return true;

}

 

I can see it moving as expected but when I'm close to it, there is lot of flickering and it is even hard to keep looking at this moving door.

 

What are the tricks to allow a smoothing move?

 

I guess there must be way to synchronize it with some refreshing update or else...

 

Thanks for your help!

Disable physics for it, using SetPosition() on physics enabled objects isn't really how you are suppose to do it. You should use forces.

 

EntityDoor->SetMass(0.0f);

 

Also note that the door prefab you are using has a connected script : SlidingDoor.lua

 

You would be better off just loading the model file (mdl) for the door in your example, not the physics enabled prefab which also has a script attached to it.

Thanks Shadmar for your quick answer!

 

So I followed your advice and used a model instead and it now moves smoothly in the sky.
