 I sort of found a workaround, where I copy the value of '''ai_name''' to '''testVar''' not directly, but via Daodan's '''sprintf''' (basically you do '''testVar = sprintf("%s",ai_name)''' instead of '''testVar = ai_name'''). This fills '''testVar''' with some garbage (in my test it was "h”å"), but it's some consistent garbage that is somehow related to '''ai_name''' - so you can use this at spawn time to initialize the "reference name" of a character, and later check against it with names that you receive from death functions, trigger volumes, etc. I didn't check this thoroughly, but I will make an illustration (probably in TCTF HQ, where many Vanilla CHARs have spawn functions). Also, I have no idea why '''sprintf''' garbles the literal like that when it comes from runtime, so that's another thing that will need to be checked. --[[User:Geyser|geyser]] ([[User talk:Geyser|talk]]) 13:56, 18 May 2020 (CEST)
+OK, good news and bad news. '''Bad:''' string management is fundamentally messy, including '''sprintf'''. Like, I was expecting '''sprintf'''-created strings to stay protected, but they're easily overwritten by other data, depending on the context - it's like the "string" is just a raw char* and there is nothing to keep track of the allocated memory at all. '''Good:''' the following works:
+ func void t48_dead(string ai_name)
+ {
+     var int index = d_getindex(ai_name);
+     var int index0 = d_getindex(A_t48);
+     if(index eq index0)
+         dmsg("A_t48 detected!")
+     else
+         dmsg("No index match!")
+ }
+or this, in TCTF HQ:
+ func void striker_spawn(string ai_name)
+ {
+ 	var int index = d_getindex(ai_name);
+ 	var int index1 = d_getindex(garage_striker_01);
+ 	var int index2 = d_getindex(garage_striker_02);
+ 	if(index eq index1)
+ 		dmsg("Striker_01 has been spawned!")
+ 	if(index eq index2)
+ 		dmsg("Striker_02 has been spawned!")
+ }
+ func void striker_die(string ai_name)
+ {
+ 	var int index = d_getindex(ai_name);
+ 	var int index1 = d_getindex(garage_striker_01);
+ 	var int index2 = d_getindex(garage_striker_02);
+ 	if(index eq index1)
+ 		dmsg("Striker_01 has died!")
+ 	if(index eq index2)
+ 		dmsg("Striker_02 has died!")
+ }
+ func void spawnStriker1(void)
+ {
+ 	chr_wait_animtype 0 punch
+ 	ai2_spawn garage_striker_01 force
+ 	sleep 60
+ 	fork spawnStriker1
+ }
+ func void spawnStriker2(void)
+ {
+ 	chr_wait_animtype 0 kick
+ 	ai2_spawn garage_striker_02 force
+ 	sleep 60
+ 	fork spawnStriker2
+ }
+ func void main(void)
+ {
+ 	fork spawnStriker1
+ 	fork spawnStriker2
+ }
+The same thing works just fine for a trigger volume, e.g., at the Airport:
+ func void fire_damage(string ai_name)
+ {
+ 	var int index = d_getindex(ai_name);
+ 	var int index0 = d_getindex(char_0);
+ 	var int index1 = d_getindex(LoadingBay_Thug_1);
+ 	var int index2 = d_getindex(LoadingBay_Thug_2);
+ 	if(index eq index0)
+ 		dmsg "Konoko is burning!"
+ 	if(index eq index1)
+ 		dmsg "Thug 1 is burning!"
+ 	if(index eq index2)
+ 		dmsg "Thug 2 is burning!"
+ }
+ func void main(void)
+ {
+ 	ai2_spawn LoadingBay_Thug_1
+ 	ai2_spawn LoadingBay_Thug_2
+ 	chr_location 0 134 -105 1029
+ }
+OK, then, problem solved, moving on. --[[User:Geyser|geyser]] ([[User talk:Geyser|talk]]) 12:39, 19 May 2020 (CEST)
