How to give locomotion to a character

[Vida Marcell]

I want to make a player that has animated movement with ik foots, how should i do that in leadwerks? like an assasins creed with fps camera.

Do you mean that if the character is on a staircase his feet accommodate each step where he places his feet?

Yes

[Yue]

The only thing I can think of is to have a beam coming out of each player's foot and these detect when the player touches the ground.  If one doesn't touch the ground depending on the leg it could trigger an animation that is one foot lower. 

Possibly there is another better way to do it.

This is smart. But i think i will focus on blending the animations. Integrating havok would help. but if someone notices it Havok will beat my ***.

Also how in the hell can i attach a cpp code to a character?

[Charrua]

HI, you can attach a lua script from the editor. If you have the profesional edition and you are using VSxxx and cpp you may interact with world elements created on the editor, call lua functions in the object's script, pass parameters, receive etc.

 

I wrote this some time ago, don't know how much outdated it may be, but perhaps it will be a starting point:

Thank you very much!

I believe there is a FindEntity command in the current world. ( map ) and another called SetScript.

Last thing, how can i make my crouch more fluid?

you need this to be a function with a tick and for every tick your camera moves a tiny bit more towards the target position.
You could use Lerp in that function : https://www.leadwerks.com/learn?page=API-Reference_Object_Math_Lerp

Good solution, thanks!

[Vida Marcell]

Is this the right way of doing it?

camera->SetPosition(0, Math::Lerp(1, -0.4, 0.5), 0);

Because its not working for me.

[Slastraf]

//might not work but is pseudo code
// Vec3 ccamerapos = ccamera->GetPosition();
// ccamera->SetPosition(0, Math::Lerp(1, ccamerapos->GetY(), (crouchedBool*(characterheight)+crouchHeight 0);

man, thank you, lemme check if its working

[Vida Marcell]

Allright, can someone tell what am i doing wrong here is a part of my code:

//Load a prefab
	Entity* player = Prefab::Load("Prefabs/player.pfb");
	player->SetPosition(0, 6, 0);
	player->SetSweptCollisionMode(true);

	Camera* camera = Camera::Create(player);
	camera->SetPosition(0, 2, 0);
	float playerheight;

	window->HideMouse();

	float walk;
	float turn;
	float jump;
	float jumpspeed = 8;
	float speed;
	bool cdown = 0;

	Vec3 mouse = Vec3(0, 0, 0);
	Vec3 velo = Vec3(0, 0, 0);
	Vec3 camera_y = Vec3(0, 0, 0);

	float mouse_x;
	float mouse_y;

	float lerp;

	while (true)
	{
		camera->GetPosition();
		camera_y = camera->GetPosition();

		mouse = window->GetMousePosition();
		window->SetMousePosition(window->GetWidth() / 2, window->GetHeight() / 2);

		mouse_x += (mouse[0] - window->GetWidth() / 2) / 4.5;
		mouse_y += (mouse[1] - window->GetHeight() / 2) / 4.5;
		
		camera->SetRotation(mouse_y, 0, 0);

		walk = window->KeyDown(Key::W) *speed - window->KeyDown(Key::S) *speed;
		turn = window->KeyDown(Key::D) *speed - window->KeyDown(Key::A) *speed;
		speed = 5 + window->KeyDown(Key::Shift) * 2 - window->KeyDown(Key::Control) * 3.5;
		
		lerp = Math::Lerp(2, 0, 0.5);
		
		if (!window->KeyDown(Key::ControlKey) && cdown == 1)
		{
			cdown = 0;
			speed = 8.0;
			camera->SetPosition(0, 1.75, 0);
		}

		if (window->KeyDown(Key::ControlKey) && cdown == 0)
		{
			cdown = 1;
			speed = 4.0;
			camera->SetPosition(0, lerp, 0);
		}

		velo = player->GetVelocity();
		if (velo[1] == 0.0)
		{
			jump = window->KeyHit(Key::Space) * jumpspeed;
		}
		else
		{
			jump = window->KeyHit(Key::Space) * 0.0;
		}

		player->SetInput(mouse_x, walk, turn, jump, cdown, 1, 1, true);
		
		if (window->Closed() || window->KeyDown(Key::Escape)) return false;
		Leadwerks::Time::Update();
		world->Update();
		world->Render();
		context->Sync();
	}
	return 0;
}

 

[Slastraf]

lerp = Math::Lerp(2, 0, 0.5);
will always make the player height zero

lerp = Math::Lerp(camera->GetPosition().y, (playerheight*cdown ), 0.5);

does this make sense to you ? camera->GetPosition().y, may be wrong but you need to get the y part of the vector of getposition
also you need to remove (makes no sense):

	while (true)
	{
		// remove this line camera->GetPosition();

[Vida Marcell]

Man, thanks for your help! If you need models or something for your game, just call me. I think i can make it work.
