Make an object point towards an object

[Master_Kenobi]

Ok so i previously posted about making a working projectile, and now im working on an enemy, but theres one problem. I need to enemy to point towards the character. I have tried this before, and also tried using it to make the gun point to the mouse, but the method in this video did not work https://www.youtube.com/watch?v=dXMV1uxjHRU&t=9s

This function should help:

this.pointTowards=function(Obj){
this.rotation = -Math.atan2(this.x - Obj.x, this.y - Obj.y) * 180 / Math.PI;
}

Here’s a project with an arrow pointing to the mouse:

I used the Math.atan2(y, x) function which calculates the rotation angle from the difference in location (the arctangent). atan2 gives the answer in radians but Wick uses degrees, so I multiplied it by 180 / pi to convert. Here’s the important line of code:

this.rotation = -Math.atan2(this.x - mouseX, this.y - mouseY) * 180 / Math.PI;

Thanks again, i looked so hard but didnt seem like many people were having the same problem
