hi all, in my spare time i made some vector geometry methods, and i thought after i made them that some people might find them usefull, i havnt added alot of features like color blending or collision but if people thought that they would like this then i would implement them :D
here is the function set
Type Vector2
Field x,y
End Type
Type Vector3
Field x,y,z
End Type
Type VectorGeomObject
Field start.VectorGeomSet
Field size
Field position.Vector2
End Type
Type VectorGeomSet
Field movement.Vector2
Field StartColor.Vector3
Field EndColor.Vector3
Field NextSet.VectorGeomSet
End Type
Function Vec2.Vector2(x,y)
v.Vector2 = New Vector2
v\x = x
v\y = y
Return v
End Function
Function Vec3.Vector3(x,y,z)
v.Vector3 = New Vector3
v\x = x
v\y = y
v\z = z
Return v
End Function
Function CreateVector(x = 0, y = 0)
v.VectorGeomObject = New VectorGeomObject
v\size = 0
v\position.Vector2 = New Vector2
v\position\x = x
v\position\y = y
Return Handle(v)
End Function
Function PositionVector(hVector,x,y)
v.VectorGeomObject = Object.VectorGeomObject(hVector)
v\position\x = x
v\position\y = y
End Function
Function AppendVector(hVector,vector.Vector2,startcolor.Vector3,endcolor.Vector3)
v.VectorGeomObject = Object.VectorGeomObject(hVector)
If v\size = 0
v\start.VectorGeomSet = New VectorGeomSet
vecset.VectorGeomSet = v\start
vecset\movement.Vector2 = vector
vecset\StartColor = startcolor
vecset\EndColor = endcolor
vecset\NextSet.VectorGeomSet = New VectorGeomSet
v\size = v\size +1
Else
vecset.VectorGeomSet = v\start
For i = 1 To v\size-1
vecset = vecset\NextSet
Next
vecset\NextSet.VectorGeomSet = New VectorGeomSet
vecset = vecset\NextSet
vecset\movement.Vector2 = vector
vecset\StartColor = startcolor
vecset\EndColor = endcolor
v\size = v\size+1
EndIf
End Function
Function GetNumVectors(hVector)
v.VectorGeomObject = Object.VectorGeomObject(hVector)
Return v\size
End Function
Function EditVector(hVector,Index,vector.Vector2,startcolor.Vector3,endcolor.Vector3)
v.VectorGeomObject = Object.VectorGeomObject(hVector)
If Index > v\size Then Return
vecset.VectorGeomSet = v\start
For i = 1 To Index-1
vecset = vecset\NextSet
Next
vecset\movement = vector
vecset\StartColor = startcolor
vecset\EndColor = endcolor
End Function
Function VectorStartColor(hVector,Index,startcolor.Vector3)
v.VectorGeomObject = Object.VectorGeomObject(hVector)
If Index > v\size Then Return
vecset.VectorGeomSet = v\start
For i = 1 To Index-1
vecset = vecset\NextSet
Next
vecset\StartColor = startcolor
End Function
Function VectorMovement(hVector,Index,vector.Vector2)
v.VectorGeomObject = Object.VectorGeomObject(hVector)
If Index > v\size Then Return
vecset.VectorGeomSet = v\start
For i = 1 To Index-1
vecset = vecset\NextSet
Next
vecset\movement = vector
End Function
Function DrawVectors()
Local x = 0
Local y = 0
For v.VectorGeomObject = Each VectorGeomObject
vecset.VectorGeomSet = v\start
x = v\position\x
y = v\position\y
For i = 1 To v\size
Color vecset\StartColor\x,vecset\StartColor\y,vecset\StartColor\z
Line x,y,vecset\movement\x+x,vecset\movement\y+y
x = x + vecset\movement\x
y = y + vecset\movement\y
vecset = vecset\NextSet
Next
Next
End Function
and here is an example
Graphics 640,480,32,2
SetBuffer BackBuffer()
xz = CreateVector(320,240)
While Not KeyDown(1)
Cls
;x = x + 3
;If x > 630 Then x = -10
Rect 310,230,20,20
If MouseDown(1)
AppendVector(xz,Vec2(MouseX()-320,MouseY()-240),Vec3(Rand(255),Rand(255),Rand(255)),Vec3(0,0,0))
Delay 100
EndIf
DrawVectors()
Flip
Wend
Please note, this was an exercise i set for myself in writing a linked list... but then i thought that it might be usefull, in the example, click the mouse in relation to the SQUARE in the center to append a vector in that direction + that magnetude
