Create a mission

Creating a mission is tough. It is recommended that you start practicing with simple threads and work your way up instead of attempting to create a mission right away. There are many ways to create a mission so to simplify this for beginners, the rest of the article will show the basic structure of creating a working mission. The format uses Sanny Builder and should work for GTA III, Vice City, and San Andreas.

Define your mission

First define your mission. Find

DEFINE MISSIONS

Increment that number by one. Scroll down until you see the last defined mission. Define your mission below it.

DEFINE MISSION {xxx} AT @MissionStart

where {xxx} is the mission index, one more from the previous mission.

Insert your trigger

Next create a thread that will trigger your mission to start. Find

create_thread

Insert before it

004F: create_thread @MissionTrigger

or

create_thread @MissionTrigger

Find

//-------------Mission 0---------------

That is where the MAIN section ends and the first mission begins. Insert your trigger between that.

:MissionTrigger 0001: wait 0 ms 00D6: if 0256: player $PLAYER_CHAR defined 004D: jump_if_false @MissionTriggerEnd 00D6: if 0038: $ONMISSION == 0 004D: jump_if_false @MissionTriggerEnd 00D6: if // Place your condition to start your mission 004D: jump_if_false @MissionTriggerEnd 0417: start_mission {xxx} 0004: $ONMISSION = 1 :MissionTriggerEnd 0002: jump @MissionTrigger

or

:MissionTrigger while true wait 0 if 0256: player $PLAYER_CHAR defined then if $ONMISSION == 0 then if // Condition to start your mission then start_mission {xxx} $ONMISSION = 1 end end end end

where {xxx} is your mission index or the label of your mission.

Insert your mission

Last insert your mission. If you are using GTA3 or Vice City, scroll all the way to the end of the file to insert your mission. If you are using San Andreas, find

//-------------External script 0 (PLAYER_PARACHUTE)---------------

That is where the last mission ends and the first external scrpt starts. Insert your mission between that.

:MissionStart 03A4: name_thread 'NAME' 0050: gosub @MissionBegin 00D6: if 0112: wasted_or_busted 004D: jump_if_false @MissionEnd 0050: gosub @MissionFailed :MissionEnd 0050: gosub @MissionCleanup 004E: end_thread :MissionBegin // This section is where you place the contents of your mission 0051: return :MissionFailed // This section is what happens after you died or got busted during your mission 0051: return :MissionCleanup // This section is where you clean up the contents of your mission so you can end it 0004: $ONMISSION = 0 00D8: mission_cleanup 0051: return

or

:MissionStart thread 'NAME' gosub @MissionBegin if wasted_or_busted then gosub @MissionFailed end gosub @MissionCleanup end_thread :MissionBegin // Place the contents of your mission return :MissionFailed // Died or got busted during your mission return :MissionCleanup // Clean up the contents of your mission so you can end it $ONMISSION = 0 mission_cleanup return
