camera look question

[aiaf]

I select a model in the scene then move around, rotate camera,

then i want to move the mouse over the previous selection

 

In some class i have this code for the camera, called in the main loop:

 camera->Move(camMovement);

 currentMousePosition = window->GetMousePosition();
 mouseDifference.x = currentMousePosition.x - centerMouse.x;
 mouseDifference.y = currentMousePosition.y - centerMouse.y;

 camRotation.x += Math::Round(mouseDifference.y / mouseSensitivity);
 camRotation.y += Math::Round(mouseDifference.x / mouseSensitivity);

 camera->SetRotation(camRotation);

 window->SetMousePosition(centerMouse.x, centerMouse.y);

 

Currently i try like this, this code is only executed once when i press space:

 

 Vec3 cu = currentUnit->GetModel()->GetPosition(true);
 Vec3 sp = camera->Project(cu);
 window->SetMousePosition(sp.x, sp.y);
 System::Print(String(sp.x) + " " + String(sp.y));

 

This kind of works but it moves the cursor sligthly off the model (seems related to SetMousePosition being called in the main loop).If i press space 3 4 times it gets in the right position.

 

Anyone can help with this ? run out of ideas maybe i should try another approach

 

Thanks

You are not showing enough information to be able to see or replicate the problem. What is setting the values for the 'centerMouse.x' and 'centerMouse.y' variables? And which 'window:SetMousePosition()' is occurring first/last? The one in the main loop or the one when the SPACE key is pressed?

This is in the camera constructor:

centerMouse = Vec2(Math::Round(context->GetWidth()/2), Math::Round(context->GetHeight()/2));

 

The camera update occurs in player->Loop and the space is pressed in console->Loop.

    running = console->Loop();
    player->Loop(window);

 

SetMousePosition is getting executed every loop in player->Loop.

Someone press space one call in consoleLoop, then it goes on until closed in player->Loop.

Nevermind this post, this was me not passing a parameter by reference, didnt need the Project function

 

Vec3 cu = currentUnit->GetModel()->GetPosition(true);
camera->SetPosition(cu.x, cu.y, cu.z - 7);
camRotation->x = 0;
camRotation->y = 0;

camera->SetRotation(*camRotation);
