simple 2D vector graphics part 25 - madscijr - 11-18-2022
Now with twinkling stars!
Code: (Select All)
Dim Shared m_sTitle As String: m_sTitle = "2D Vector Shapes v0.20 by madscijr"
_Title m_sTitle ' display in the Window's title bar
' Simple test of vector graphics,
' borrowed graphics objects and format from Widescreen Asteroids by Terry Ritchie.
' DONE
' * We now can draw opaque shapes (still need to get working for shapes with non-contiguous areas)
' * Display looks prettier!
' - Shapes not active are drawn in an animated dashes
' - Text display is color coded to shapes
' * Tried adding twinkling stars (hard to see, need to fix)
' TO DO:
' * fix twinkling stars
' * encapsulate drawing shape in one routine
' * get fill working for shapes with non-contiguous areas)
' - define "fill coordinates" property or array
' - auto find these in shape
' - eliminate duplicates
' - store the remaining values store in shape data
' - use for PAINT when drawing fill color

' Revision: 1.6

'SUMMARY:
'[Replace$] replaces all instances of the [Find] sub-string with the [Add] sub-string within the [Text] string.
'INPUT:
'Text: The input string; the text that's being manipulated.
'Find: The specified sub-string; the string sought within the [Text] string.
