I wrote this class based on the math that I could derive from the context clues in the materials I studied on vectors, the problem is that there was only so far I could go using that method and because I was always missing a big piece of the puzzle, there has always been a limit on how much I can do or learn to do with vector math. Hopefully there are some people out there that know some of the missing functions to make this a more complete lib.
If you know a missing function, please share.
Code: Select all
Class HB_Vector {
__New(x:=0,y:=0){
This.X:=x
This.Y:=y
}
Add(Other_HB_Vector){
This.X+=Other_HB_Vector.X
This.Y+=Other_HB_Vector.Y
}
Sub(Other_HB_Vector){
This.X-=Other_HB_Vector.X
This.Y-=Other_HB_Vector.Y
}
mag(){
return Sqrt(This.X*This.X + This.Y*This.Y)
}
magsq(){
return This.Mag()**2
}
setMag(in1){
m:=This.Mag()
This.X := This.X * in1/m
This.Y := This.Y * in1/m
return This
}
mult(in1,in2:="",in3:="",in4:="",in5:=""){
if(IsObject(in1)&&in2=""){
This.X*=In1.X
This.Y*=In1.Y
}else if(!IsObject(In1)&&In2=""){
This.X*=In1
This.Y*=In1
}else if(!IsObject(In1)&&IsObject(In2)){
This.X*=In1*In2.X
This.Y*=In1*In2.Y
}else if(IsObject(In1)&&IsObject(In2)){
This.X*=In1.X*In2.X
This.Y*=In1.Y*In2.Y
}
}
div(in1,in2:="",in3:="",in4:="",in5:=""){
if(IsObject(in1)&&in2=""){
This.X/=In1.X
This.Y/=In1.Y
}else if(!IsObject(In1)&&In2=""){
This.X/=In1
This.Y/=In1
}else if(!IsObject(In1)&&IsObject(In2)){
This.X/=In1/In2.X
This.Y/=In1/In2.Y
}else if(IsObject(In1)&&IsObject(In2)){
This.X/=In1.X/In2.X
This.Y/=In1.Y/In2.Y
}
}
dist(in1){
return Sqrt(((This.X-In1.X)**2) + ((This.Y-In1.Y)**2))
}
dot(in1){
return (This.X*in1.X)+(This.Y*In1.Y)
}
cross(in1){
return This.X*In1.Y-This.Y*In1.X
}
Norm(){
m:=This.Mag()
This.X/=m
This.Y/=m
}
}
If you are interested in vectors as a topic, I recommend this series on youtube by 3Blue1Brown on Linear Algebra
