# How to use:
#	1. Set up a token ID in common/ideas/zzz_Alerts.txt henceforth refered to as <token ID>
#		- Add an on_add to assign a sound effect to your alert as it gets added
#	2. Set up the GFX in interface/md_alerts.gfx as GFX_<token ID>
#		- Place the GFX file under gfx/interface/md_alerts/
#		- Template is available in that folder, named blank.dds
#	3. Set up any effects that clicking your alert does in common/scripted_effects/md_alerts_scripted_effect.txt
#		- Do this under the md_alert_click effect
#	4. Localize the alert in localisation/<language>/md_alerts_l_<language>.yml
#		- The loc key as <token ID> and description as <token ID>_Desc (it is important that the D is capitalized)
#		- If you would like to do custom scripted localisation here, use common/scripted_localisations/md_alerts_scripted_localisation.txt
#	5. In order to show an alert, do the following:
#
#		set_temp_variable = { alert_id = token:<token ID> }
#		set_temp_variable = { alert_color = (1/2) }			# 1 is for a yellow glow while 2 is for a red glow
#		set_temp_variable = { alert_data = <...> }			# (Optional) This can be used to store any sort of data that corresponds to the alert
#		add_md_alert = yes									# alternatively, add_md_alert_unless_exists
#
#	6. In order to remove an alert, do the following:
#
# 		set_temp_variable = { alert_id = token:<token ID> }
#		remove_md_alert = yes


# Scripted effects for custom alert system ported from TNO
# Set up any effects that clicking your alert does under md_alert_click
