Mode07 on the Map!
Includes:
Mode07 v0.6
Overworld Sprite Resize
Written by mewsterus
Special Thanks:
Fanha Giang (for a reverse engineered Tilemap class)
--------------------------------------------------------------------------------
Instructions:
--------------------------------------------------------------------------------
To install, just insert this in a descriptive code slot right above Main.
This is different than previous instructions; please read the next paragraph.
If you had a previous install of this script and need an original version of
Spriteset_Map, one can be found at:
http://www.rpg-palace.com/scripts/spriteset_map.txt
To activate Mode07, add [#XX] to the map's name, replacing XX with the
percentage of Mode07 to apply. Greater numbers will result in a more slanted
world.
To activate overworld sprite resize, add [OV] to the map's name. This will make
sprites smaller on that map.
For the purposes of location scripts, these identifiers will not appear.
Examples:
"Overworld[#40]" will result in a slant identical to the second screenshot.
"Underworld[OV]" will resize only the player character to a small size, as if
seen from high above.
"Atthelevelworld[OV][#12]" will result in the player being resized, and a modest
slant of 12%
"JustPlainWorld" will result in the same old map you've always seen.
To add a sky, simply use the panorama with the tileset. Also, events will not
be drawn flat with the map. Any vertical objects such as trees should be put
in events and displayed that way.
You can also add a sky by adding a fog. If you add this, you can make it look
like the first screenshot.
A note on the $strip_size variable; the default value is 8, however there is
extremely minimal, almost nonexistant lag with 16. The screen is extremely
smooth with 4, or even 2. If you're having major problems with lag, you may
need to use 32, but it won't look too pretty.
