This project is from 12 years ago...
I can easily describe an example verbally; let's take the alien girl Ella as an example.
Each time you wake up, a check is performed (note that facial expressions are created separately so they can be directly applied):
Event Branch:
Ella is in the party: true
[Item check "Ellabelly"]
IF item count is 0-10, then display image EllaB1
Display image EllaF2
Use text: "XXXXX"
IF item count is 11-30, then display image EllaB2
Display image EllaF2
Use text: "XXXXX"
IF item count is 31-50, then display image EllaB3
Display image EllaFB2 (facial position shifted due to different images)
Use text: "XXXX"
Character speed is -1
The protagonist turns to the side (because the belly is too big to wash from the front)
IF item count is 51-70, then display image EllaB4
Display image EllaFB2 (facial position shifted due to different images)
Use text: "XXXX"
Character speed is -1
The protagonist turns to the side
IF item count is 71-90, then display image EllaB5
Displays image EllaFB4 (face position shifted due to image difference)
Text: "XXXX"
Character speed -2
IF Item count 91+ or less, then display image EllaB6
Displays image EllaFA1 (face position shifted due to image difference)
Text: "XXXX"
Special event: Character leaves the party. Ella airship switch is NO.
(The above can be applied to other events. Note the speed setting for deletion. Each character needs a set of cluster judgments; otherwise, images may appear even when the character is not in the party.)
Image deleted!
...Specific room door:
IF Ella in party true
IF Ellabelly count 51-70, then display image EllaB4
Displays image character name FB2
Text: "Hope the door frame doesn't break..."
Sound effect
Map relocation
IF Ellabelly count 71-90, then display image EllaB5
Displays image EllaFB4
Text: "Too big, can't get in..."
Image deleted!
IF Ishura in the team::true
IF Ishura's belly count is between 51 and 70, then display image Ishura B4
Display image Ishura FB2
Text: "I need... to squeeze a little harder"
Image deleted!
Sound effect
Map relocation
IF Ishura's belly count is between 71 and 90, then display image Ishura B5
Display image Ishura FB4
Text: "Even if I break down the door, I still can't get in..."
IF Quinn in the team: true
IF Quinn's belly count is between 51 and 70, then display image Quinn B4
Display image Quinn FB3
IF Quinn's belly count is between 71 and 90, then display image Quinn B5
Display image Quinn FB3
Text: "You think I can squeeze through a door the size of a human?"
Image deleted!
(She's an anthropomorphic dragon, so she can't enter most doors; only her character portrait needs to be checked.) Character Action: The protagonist takes one step back (Note this is the final check; otherwise, the protagonist will retreat three times due to multiple characters in the party).
Important: Delete the image!

Oh, by the way, this is something I helped another author create... The "pregnant woman's" walking image isn't simply "adding a sphere," but rather requires adjusting the upper body to move back slightly. Because of the pressure on the pelvis, the legs walk more like a penguin or a duck.
