3D-Ish Twirling Sprite Character

Post by NorbyDroid »

Here is something I thought would be fun to share. It show off what can be done with a sprite sheet of a character and the 'Put' statement.

Code: Select all

#Include "fbgfx.bi"

WindowTitle "Spinning Character"

Dim as Boolean Done
Dim as String Touch

Dim as Integer Frame
Dim as FB.Image Ptr Girl, Girl3D

ScreenRes 640, 480, 32

Sub Create3D(Image1 as FB.Image Ptr, Image2 as FB.Image Ptr)
  Dim as Integer xPos

  Dim tImage as FB.Image Ptr
  tImage=ImageCreate(32, 48, 32)

  For Frame as Integer=0 to 63
    Line tImage, (0, 0)-(2047, 47), RGB(255, 0, 255), bf

    If Frame<16 then
      Put tImage, (Frame, 0), Image1, (Frame, 0)-(31-Frame, 47), Trans
      Put tImage, (0, 0), Image1, (0, 48)-(Frame, 95), Trans
      Put tImage, (31-Frame, 0), Image1, (31-Frame, 48)-(31, 95), Trans
    EndIf

    If Frame>15 and Frame<32 then
      Put tImage, (Frame-16, 0), Image1, (Frame-16, 48)-(31-(Frame-16), 95), Trans
      Put tImage, (0, 0), Image1, (0, 144)-(Frame-16, 191), Trans
      Put tImage, (31-(Frame-16), 0), Image1, (31-(Frame-16), 144)-(31, 191), Trans
    EndIf

    If Frame>31 and Frame<48 then
      Put tImage, (Frame-32, 0), Image1, (Frame-32, 144)-(31-(Frame-32), 191), Trans
      Put tImage, (0, 0), Image1, (0, 96)-(Frame-32, 143), Trans
      Put tImage, (31-(Frame-32), 0), Image1, (31-(Frame-32), 96)-(31, 143), Trans
    EndIf

    If Frame>47 then
      Put tImage, (Frame-48, 0), Image1, (Frame-48, 96)-(31-(Frame-48), 143), Trans
      Put tImage, (0, 0), Image1, (0, 0)-(Frame-48, 47), Trans
      Put tImage, (31-(Frame-48), 0), Image1, (31-(Frame-48), 0)-(31, 47), Trans
    EndIf

    Put Image2, (32*xPos, 0), tImage, (0, 0)-(31, 47), PSet
    xPos+=1
  Next

  ImageDestroy tImage
End Sub

Girl=ImageCreate(128, 192, 32)
Bload "Girl.bmp", Girl

Girl3D=ImageCreate(2048, 47, 32)
Create3D Girl, Girl3D

Frame=0
While Not Done
  Touch=Inkey
  If Touch=Chr(27) then Done=True

  Line(0, 0)-(31, 47), RGB(0, 0, 0), bf
  Put(0, 0), Girl3D, (32*Frame, 0)-(32*Frame+31, 47), Trans

  Frame+=1 : If Frame=64 then Frame=0
  Sleep 15
Wend

ImageDestroy Girl
ImageDestroy Girl3D
The code loads a sheet with a girl character, then creates a 3D-like image of the girl as she spins around clockwise. Enjoy.
