Solved- How to rotate player using Dot product of two vectors

I got it working, I was overcomplicating things by using the Mathf.Cos function, because the Dot product is the cosign of the angle, so I’m not sure what i was thinking. here is the working code for anyone curious. camRotation = player.transform.rotation.x + player.transform.rotation.y * Input.mousePosition.x + Input.mousePosition.y; player.transform.rotation = Quaternion.Euler(0, 0, camRotation); >Solution :… Read More Solved- How to rotate player using Dot product of two vectors

How to rotate a triangle about it's center?

document.onkeydown = function (event) { switch (event.keyCode) { case 74: //player presses "j" px = player.calculateCentreX(); py = player.calculateCentreY(); x1 = rotateX(player.x1,player.y1,35,px,py); x2 = rotateX(player.x2,player.y2,35,px,py); x3 = rotateX(player.x3,player.y3,35,px,py); y1 = rotateY(player.x1,player.y1,35,px,py); y2 = rotateY(player.x2,player.y2,35,px,py); y3 = rotateY(player.x3,player.y3,35,px,py); player.setPoints(x1,y1,x2,y2,x3,y3); break; default: break; } }; function rotateX(cx,cy,angle,px,py) { x = Math.cos(angle)*(px-cx) – Math.sin(angle)*(py-cy) + cx return x… Read More How to rotate a triangle about it's center?

Displaying percentages within category for continuous/ordered variable (with ggplot)

I have two questions, the first a (hopefully) straightforward mechanical one and the second more theoretical (though still with a technical element). I am trying to do something nearly identical to this question, but I have a variable that is ordered/continuous (0 – 4), instead of a 1/0 dichotomous variable, which means that filtering ==… Read More Displaying percentages within category for continuous/ordered variable (with ggplot)

How can I toggle this dropdown?

I have tried adding a simple toggle function to the dropdown-btn class which in turn adds the active class (which is set to display: block;) onto the ul class, am I doing anything wrong here? https://jsfiddle.net/q45yc3vt/10/ HTML <nav class="admin-sidebar sidebar"> <div class="sidebar-nav"> <li><a href="#" class="dropdown-btn"><i class="fas fa-address-card"></i><span>Dropdown</span><i class="fas fa-angle-down"></i></a></li> <ul class="options"> <li>Option 1</li> <li>Option 2</li>… Read More How can I toggle this dropdown?
