[LE3-SOLVED] Character physics bug?

[AggrorJorn]

I am not sure if I am doing something wrong or whether this is a bug. My characters movement seems to work fine at first, but after some walking around, I notice that the strafing no longer works correct. sometimes I go into the opposite direction of where I want to go. The example attached shows that strafe walking doesn't function properly and that jumping has some issues as well.

 

 

 

//Get the mouse movement
Vec3 currentMousePos = window->GetMousePosition();
mouseDifference.x = currentMousePos.x - centerMouse.x;
mouseDifference.y = currentMousePos.y - centerMouse.y;


//Adjust and set the camera rotation
camRotation.x += mouseDifference.y / mouseSensitivity;
camRotation.y += mouseDifference.x / mouseSensitivity;
camera->SetRotation(camRotation);
window->SetMousePosition(centerMouse.x, centerMouse.y);


//Player Movement
playerMovement.x = (window->KeyDown(Key:) - window->KeyDown(Key::A)) * Time::GetSpeed() * strafeSpeed;
playerMovement.z = (window->KeyDown(Key::W) - window->KeyDown(Key::S)) * Time::GetSpeed() * moveSpeed;

//Update the player
player->SetInput(camRotation.y, playerMovement.z, playerMovement.x, 0, crouched, 0.5);

Vec3 playerPos = player->GetPosition();
camera->SetPosition(playerPos.x, playerPos.y + 1.8, playerPos.z);

 

 

Jumping also has problems. I have this really simple code that lets the player jump. Unfortunately this only works sporadicly, after hitting the space key a 10 to 20 times. The weird thing is, when you leave out the check for the Space key being pressed, the character jumps perfectly normal (although it keeps jumping ofcourse, since we no longer check for key pressing).

 

// Check for jumping
float tempJumpForce = 0;
if(window->KeyHit(Key::Space) && player->GetAirborne())
tempJumpForce = 10;

//Update the player
player->SetInput(0, 0, 0, tempJumpForce , false, 1);

Any body else getting these results?

When I wanted to record the project to show what is going on, somehow the jumping worked. It turns out that the FPS causes the jumping to either work or not work. After setting the vsync to true (60 fps) jumping works normally. without vsync I have 800 fps.

The physics is updated at 60 hz, regardless of framerate. It's really best to call SetInput in the UpdatePhysics callback, because then you can be sure jumps will make it into the next physics update.

Okay thanks, that solves the jumping problem. Any idea on the strafing?

I will test it when we get back.

The strafe is a known bug, I reported it while back.

Thank you Andy.
