Im trying to run a script called guild fisher i DL the old includes but i get this message

Failed when compiling
Line 345: [Error] (392:4): Unknown identifier 'IsTextAt2' in script C:\Program Files\SCAR 3.13\includes\osi.txt

If anyone can help me I would greatly appreciate it, Im running it on Scar 3.13

 

It's an outdated include, you will need to find a newer script.

 

OSI.txt is a ver small include, can easyily be fixed to work BUT IsTextAt2 is not in SCAR DIVI you will have to change all IsTextAt2 to another text function. Even if you got it working tho it would be a pain to update the old script, so in conclusion use SRL scripts for the time being.
