NOTE: UNDER ACTIVE DEVELOPMENT - THERE ARE BUGS/GLITCHES
|
||||||
|
|
||||||
|
What is this?
|
||||||
|
~~~~~~~~~~~~~
|
||||||
|
This extension provides drawing routines that are compatible with
|
||||||
|
changeable world and screen spaces. For example you can pan and
|
||||||
|
zoom, and all PGE drawing routines will automatically adopt the current
|
||||||
|
world scales and offsets.

Revisions:
|
||||||
|
1.00: Initial Release
|
||||||
|
1.01: Fix for rounding error when scaling to screen
|
||||||
|
1.02: Added DrawLineDecal for convenience
|
||||||
|
1.03: Removed std::floor from WorldToScreen()
|
||||||
|
Added HandlePanAndZoom(...) convenience function
|
||||||
|
Removed unused "range" facility in TileTransformView
|
||||||
|
1.04: Added DrawPolygonDecal() for arbitrary polygons
|
||||||
|
1.05: Clipped DrawSprite() to visible area, massive performance increase
|
||||||
|
1.06: Fixed error in DrawLine() - Thanks CraisyDaisyRecords (& Fern)!
|
||||||
|
1.07: +DrawRectDecal()
|
||||||
|
+GetPGE()
|
||||||
|
1.08: +DrawPolygonDecal() with tint overload, akin to PGE
|
||||||
|
1.09: +SetScaleExtents() - Sets range that world scale can exist within
|
||||||
|
+EnableScaleClamp() - Applies a range that scaling is clamped to
|
||||||
|
These are both useful for having zoom clamped between a min and max
|
||||||
|
without weird panning artefacts occuring
