fixed bug with not saving editor cascade settings for two element groups

This bug was caused by adding two new element groups to the level
editor palette area (for Mirror Magic and Deflektor elements), but not
adding them to the list of cascade settings to be saved.

The real problem was that two lists were kept in "src/files.c" for the
settings, and only one was updated when adding the new cascade groups.

To prevent similar bugs in the future, one of the two lists was
removed, as those definitions were not used anyway in this case.

fixed bug with CE actions "show envelope" and "exit player" when moving

When using the CE actions "show envelope" or "exit player" with the
condition "after explosion of player", those actions are not performed
if the player was moving at the time of explosion, as they are both
waiting for the player to reach the next tile (which will never happen
in this case).

The best solution is to only check for a "non-moving" tile position of
the player if the player is still active, which will fix the problem.

However, as the check for a "non-moving" tile position is used very
frequently, setting the tile position to "non-moving" for inactive
players was added.

4 years agoadded support for dynamic window and playfield size
Holger Schemel [Sat, 1 Dec 2018 11:30:29 +0000 (12:30 +0100)]
added support for dynamic window and playfield size

This change added a few new and extended directives for the graphics
configuration done in "graphicsinfo.conf" files in artwork and level

For the window and playfield definitions, there are new properties
".min_width" / ".min_height" and also ".max_width" / ".max_height"
to define minimum and maximum window and playfield sizes. This is
useful to dynamically support different screen sizes which have a
different screen aspect ratio (like tablets with 4:3 or 16:9 sized
screens), always using the full screen size without black borders
that cannot be used for the game.

To be able to place the "doors" (game panel and tape recorder) also
dynamically aligned with the right or bottom screen border, margins
can be defined for the playfield to not use these areas, which can
then be used for the doors being aligned to the corresponding window
edges. That's what the new ".margin_left", ".margin_right",
".margin_top" and ".margin_bottom" directives are for, together with
".align" and ".valign" properties to align the playfield or the doors
horizontally ("left", "center" or "right") or vertically ("top",
"middle", or "bottom").

To make sure that the game playfield always uses complete tiles (or
half tiles, or any other size), there's also a new directive called
".align_size" to specify the alignment tile size for the playfield
(which is set to half a tile by default).

The last enhancement extends playfield border sizes to be defined
for each border individually, so instead of a unique ".border_size"
for all playfield borders, different border sizes can be specified
by using ".border_left", ".border_right", ".border_top" and
".border_bottom". If they are not set, they inherit their value from
".border_size" just like before. Using the value "-1" causes borders
to be calculated dynamically -- this only makes sense when using a
variable window size (by using ".min_width" and/or ".min_height") with
a fixed playfield size, so borders can also have variable size. This
is mainly useful for using a fixed (or limited, by ".max_width/height)
playfield size while still being able to display global animations on
the whole surrounding playfield border area.

added support for dynamically sized (and placed) editor palette

When using the value "-1" for columns or rows of the editor palette
(that is, values "editor.palette.cols" and "editor.palette.rows"),
these numbers are dynamically calculated according to the size of the
editor playfield area.

When setting "editor.palette.x" or "editor.palette.y" to "-1", also
the position of the editor palette is dynamically calculated (to be
centered within the playfield area).

(As these values for columns and rows are used at a very early stage
in the level editor to allocate memory for palette buttons, make sure
that no negative numbers are used here for memory calculations.)
