AFSM (File Format): Difference between revisions

The '''AFSM format''' controls AI behavior; it stands for '''A'''I '''F'''inite '''S'''tate '''M'''achine. AI-controlled creatures have a limited number of possible states they can be in. The AFSM file defines those states, and what triggers can cause it to advance to another state.

{{researchminor|reason=We should have a list of possible states and trigger conditions and a short explanation of what they generally do on this page somewhere. Also, the float settings on conditions is unknown.}}

The format first defines a list of states, then defines each trigger attached to each state. There are no state/trigger type IDs; rather, the name string itself is used as an identifier to fetch the corresponding AI function. It starts with a short header listing each state and then providing a trigger count. Note that the trigger count isn't actually used to parse the file; it's present merely because the game uses it to allocate space for each trigger ahead of time.

| '''Condition count'''

=== State Triggers ===

Following that, it iterates through each state, defining the triggers associated with each one. Triggers are composed of a target state index and a number of conditions; when all the conditions associated with a trigger are satisfied, it advances to the targeted state. The state trigger definitions are structured like this:

| '''Trigger count''' (TC)

| Trigger

| '''Triggers'''

=== Trigger ===

| '''Condition count''' (CC)

| Trigger condition

| CC

| '''Conditions'''

=== Condition ===

| '''Condition name''' (zero terminated)

| '''Target state index''' (note: this is ONLY present on the first condition for each trigger!)
