In Idle State, our AI can randomly choose between any number of idle animations.
There are two lists of possible idle anims stored in the AI's DEF file, which can easily be overridden in the editor.
One list is containing the animations played on the ANIMCHANNEL_TORSO only. These are suitable for all kinds of idling AI (sitting, walking, whatever).
The second list is containing the animation statenames of anims playing on TORSO and LEGS channel. These are activated when the AI's LEGS channel is playing the Idle animation (which is true for a standing guard, but not for a patrolling one).
Take a look at tdm_ai_base.def:
"idle_animations" "itch,idle_arm_scratch,idle_sneeze" "idle_animations_torso" "Itch,idle_arm_scratch,idle_cough" "idle_animations_interval" "25" // seconds
The animation list is comma- or space-separated and can be any length. The names refer to the "anim" names in the AI's modelDef, (for humanoids, that is tdm_ai_guard_proguard_devel.def) e.g.:
anim idle models/md5/chars/guards/proguard/idle.md5anim anim idle_armwipe models/md5/chars/guards/proguard/idle_armwipe.md5anim anim idle_arm_scratch models/md5/chars/guards/proguard/idle_arm_scratch.md5anim anim idle_torch models/md5/chars/guards/proguard/idle_torch.md5anim anim idle_sneeze models/md5/chars/guards/proguard/idle_sneeze.md5anim
The interval is measured in seconds and an uncertainty of plus/minus 20% is automatically applied by the SDK code. Set this to zero or negative values disables the idle animations on this AI.
