How to increase the speed when I move camera via keyboard

[leon.dong]

I've tried to call 

Unigine::Game::get()->getPlayer().get()->setVelocity(Unigine::Math::vec3(5000.f,0.f,0.f));

but it seems not what I expected. I just want to fly qicker by using keyboard or mouse in runtime . 

Is there any solution ? thanks.

Hello!

to increase speed of Player spectator you need to change MinVelocity for usual moving and MaxVelocity for moving with shift key

if you wand to change it in runtine - methods has the same name

Unigine::Game::get()->getPlayer()->setMinVelocity(50);
Unigine::Game::get()->getPlayer()->setMaxVelocity(100);

https://developer.unigine.com/en/docs/2.17/api/library/players/class.playerspectator?rlang=cpp&words=player%2Cplayerlll%2Cplayerll#setMinVelocity_float_void
https://developer.unigine.com/en/docs/2.17/api/library/players/class.playerspectator?rlang=cpp#setMaxVelocity_float_void

Thanks,very helpful . @cash-metall

I have no idea how to convert Player object to PlayerSpectator , one is base virtual class, one is derived class , why failed to convert ? 

The second line has error 

	Unigine::Player* myPlayer = Unigine::Game::get()->getPlayer().get();
	Unigine::PlayerSpectator* myRealPlayer =(Unigine::PlayerSpectator*)myPlayer;

	myRealPlayer->setMinVelocity(50);
	myRealPlayer->setMaxVelocity(100);

Find a stupid way to solve it . 

I modifed my code in UnigineScript

int init() {
	// Write here code to be called on world initialization: initialize resources for your world scene during the world start.
	
	Player player;
	PlayerSpectator tempPlayer= new PlayerSpectator();
	tempPlayer.setPosition(Vec3(0.0f,-3.401f,1.5f));
	tempPlayer.setDirection(Vec3(0.0f,1.0f,-0.4f));
	tempPlayer.setMaxVelocity(200.f);
	player=tempPlayer;
	engine.game.setPlayer(player);
	return 1;
}

 Still want response from offical support why error in C++ code.

im sorry it`s my fault:  i forgot about cast to PlayerSpectator

Unigine::PlayerPtr player = Unigine::Game::getPlayer();
if (player)
{
    Unigine::PlayerSpectatorPtr spectator = Unigine::checked_ptr_cast<Unigine::PlayerSpectator>(player);
    if (spectator)
    {
        specatator->setMinVelocity(50);
        // do something else
    }
    else
    {
        Unigine::Log::error("current player is not PlayerSpectator\n");
    }
}
else
{
    Unigine::Log::error("can not find MainPlayer\n");
}

May I ask where defined 

Unigine::checked_ptr_cast

Confused , how to cast Player object to PlayerSpectatorPtr object in C++ codes......

 

[cash-metall]

checked_ptr_cast<> - universal way
dynamic_ptr_cast<> instead of dynamic_cast
static_ptr_cast<> instead of static_cast

https://developer.unigine.com/en/docs/2.17/code/fundamentals/smartpointers?rlang=cpp#upcast_downcast

I know what's wrong . 

My SDK version is v2.7..1 too old to use this new API dynamic_ptr_cast  

Is there any old API to do same thing ? 

[cash-metall]

in 2.7.1 it is 
PlayerPersecutorPtr persecutor = PlayerPersecutor::cast(player);

[leon.dong]

That works . thanks.
