Fixed..sorry bout the complexity....Ill have to make it easier somehow...not sure how though !

Found a bug !...the filetypes must be lowercase eg. ".bmp" not ".BMP"

=====================================

1) Copy the image you want (the carrot)
2) Open the directory with the editor in and go into the folder named particles, paste the image there.

3) Load my level editor
4) click place entity - click particle Source

5) Click Set texture
6) Click the up arrow until you see you carrot


7) Setup the values
