chatmessage

Datum for generating a message overlay on the map

Vars
animate_lifespan	Our animation lifespan, how long this message will last
animate_start	When we started animating the message
approx_lines	Contains the approximate amount of lines for height decay
current_z_idx	The current index used for adjusting the layer of each sequential chat message such that recent messages will overlay older ones
message	The visual element of the chat messsage
message_source	The original source of this message
message_turf	Current turf this message registered on
owned_by	The client who heard this message
signal_targets	The list of locs chained from message_source to the turf level We need to listen for possible Moved() on all of these locs and change message loc accordingly
Procs
New	Constructs a chat message overlay
colorize_string	Gets a color for a name, will return the same color for a given string consistently within a round.atom
finish_image_generation	finishes the image generation after the MeasureText() call in generate_image(). necessary because after that call the proc can resume at the end of the tick and cause overtime.
generate_image	Generates a chat message image representation
get_current_alpha	Returns the current alpha of the message based on the time spent
on_parent_qdel	Calls qdel on the chatmessage when its parent is deleted, used to register qdel signal

Var Details

var
animate_lifespan
–

Our animation lifespan, how long this message will last

var
animate_start
–

When we started animating the message

var
approx_lines
–

Contains the approximate amount of lines for height decay

var
current_z_idx
– /static

The current index used for adjusting the layer of each sequential chat message such that recent messages will overlay older ones

var
message
– /image

The visual element of the chat messsage

var
message_source
– /atom

The original source of this message

var
message_turf
– /turf

Current turf this message registered on

var
owned_by
– /client

The client who heard this message

var
signal_targets
– /list

The list of locs chained from message_source to the turf level We need to listen for possible Moved() on all of these locs and change message loc accordingly

Proc Details

New
(text, /atom/target, /mob/owner, /datum/language/language, /list/extra_classes, lifespan)

Constructs a chat message overlay

Arguments:

text - The text content of the overlay
target - The target atom to display the overlay at
owner - The mob that owns this overlay, only this mob will be able to view it
language - The language this message was spoken in
extra_classes - Extra classes to apply to the span that holds the text
lifespan - The lifespan of the message in deciseconds

proc
colorize_string
(name, sat_shift, lum_shift)

Gets a color for a name, will return the same color for a given string consistently within a round.atom

Note that this proc aims to produce pastel-ish colors using the HSL colorspace. These seem to be favorable for displaying on the map.

Arguments:

name - The name to generate a color for
sat_shift - A value between 0 and 1 that will be multiplied against the saturation
lum_shift - A value between 0 and 1 that will be multiplied against the luminescence

proc
finish_image_generation
(mheight, /atom/target, /mob/owner, complete_text, lifespan)

finishes the image generation after the MeasureText() call in generate_image(). necessary because after that call the proc can resume at the end of the tick and cause overtime.

proc
generate_image
(text, /atom/target, /mob/owner, /datum/language/language, /list/extra_classes, lifespan)

Generates a chat message image representation

Arguments:

text - The text content of the overlay
target - The target atom to display the overlay at
owner - The mob that owns this overlay, only this mob will be able to view it
language - The language this message was spoken in
extra_classes - Extra classes to apply to the span that holds the text
lifespan - The lifespan of the message in deciseconds

proc
get_current_alpha
(time_spent)

Returns the current alpha of the message based on the time spent

proc
on_parent_qdel
()

Calls qdel on the chatmessage when its parent is deleted, used to register qdel signal
