Is it possible to have a source command read a variable from an NPC script?

[michaelsoftman]

Here's the simplest example I can think of.

You do a quest, at the end the NPC sets a variable to 1 instead of 0.

In the source code, is there a way to actually check this variable for use in a function?

Here's how you can read char and account integer variables:

pc_readreg(sd, "char_var")

pc_readaccountreg(sd, "#account_var")

In trunk/src/map/pc.h you can see all the pc_read***** function names

int pc_readparam(struct map_session_data*,int);
int pc_setparam(struct map_session_data*,int,int);
int pc_readreg(struct map_session_data*,int);
int pc_setreg(struct map_session_data*,int,int);
char *pc_readregstr(struct map_session_data *sd,int reg);
int pc_setregstr(struct map_session_data *sd,int reg,const char *str);

#define pc_readglobalreg(sd,reg) pc_readregistry(sd,reg,3)
#define pc_setglobalreg(sd,reg,val) pc_setregistry(sd,reg,val,3)
#define pc_readglobalreg_str(sd,reg) pc_readregistry_str(sd,reg,3)
#define pc_setglobalreg_str(sd,reg,val) pc_setregistry_str(sd,reg,val,3)
#define pc_readaccountreg(sd,reg) pc_readregistry(sd,reg,2)
#define pc_setaccountreg(sd,reg,val) pc_setregistry(sd,reg,val,2)
#define pc_readaccountregstr(sd,reg) pc_readregistry_str(sd,reg,2)
#define pc_setaccountregstr(sd,reg,val) pc_setregistry_str(sd,reg,val,2)
#define pc_readaccountreg2(sd,reg) pc_readregistry(sd,reg,1)
#define pc_setaccountreg2(sd,reg,val) pc_setregistry(sd,reg,val,1)
#define pc_readaccountreg2str(sd,reg) pc_readregistry_str(sd,reg,1)
#define pc_setaccountreg2str(sd,reg,val) pc_setregistry_str(sd,reg,val,1)
int pc_readregistry(struct map_session_data*,const char*,int);
int pc_setregistry(struct map_session_data*,const char*,int,int);
char *pc_readregistry_str(struct map_session_data*,const char*,int);
int pc_setregistry_str(struct map_session_data*,const char*,const char*,int);

Here's how you can read char and account integer variables:

pc_readreg(sd, "char_var")

I'm a bit unsure on how to use this, because it takes an int value for the 2nd parameter where "char_var" is, so I can't use my actual variable name.

If I try using a variable name without the quotes, it says it's unidentified.

Permanent Char Variables (integer):

pc_readreg(sd, add_str("char_var"))

Permanent Char Variables (string):

pc_readregstr(sd, add_str("char_var$"))

[Emistry]

try this ?

to set...

pc_setglobalreg(sd,"char_var", <value>);

to read....

pc_readglobalreg(sd, "char_var")
