sp_brain

Prototypeint sp_brain(int active_sprite, int brain[-1])

sp_brain() gets or sets the brain for the active_sprite.

A brain defines how a sprite behaves. Several sprite functions are only compatible with specific brains.

Brain	Name	Description
0	None	No pre-defined behavior.
1	Human/Dink	Player-controlled via keyboard, and gamepad input.
2	Bounce	Sprite will bounce back and forth across the screen. No known practical uses.
3	Duck	A duck that walks around, randomly playing sound 1 (a duck's quack). First time hit, will create a new sprite use pseudo-base sequence 120 to make the duck's head fly off. The duck will use base sequence 110 to walk around, and play random blood spurts. Second time hit, will kill the sprite, and play sequence 164.
4	Pig	A pig that walks around, randomly playing sounds 2, 3, 4, and 5 (pig grunts). If killed, will play sequence 164.
5	Sequence (corpse)	Plays through the current sequence and kills the sprite, but leaves the last frame drawn to the background.
6	Repeat	Will repeat the current sequence over and over again.
7	Sequence (No trace)	Plays through the current sequence and kills the sprite, and does not leave any trace behind.
8	Text	Probably a text sprite.
9	Diagonal enemy	An enemy that constantly walks around using directions 1, 3, 7, and 9. Will attack if proper values (sp_base_attack(), sp_distance(), sp_range(), sp_attack_wait()) are set.
10	Lateral enemy	An enemy that constantly walks around using lateral directions 2, 4, 6, and 8. Will call attack procedure based on sp_attack_wait().
11	Missile (repeat)	Will repeat the current sequence over and over again, and damage sprites in range.
12	Scale	Shrinks or grows to match the size value stored in sp_brain_parm() and kills the sprite.
13	Mouse	Player-controlled via mouse input.
14	Button	Calls buttonon() and buttonoff() functions in the sprite's script if sprite 1 (Dink) is within its hardbox.
15	Shadow	Mirrors the parent sprite's (stored in sp_brain_parm()) attributes x, y, and size. Will die automatically with the parent sprite.
16	Smart	The sprite will walk around, stop, look around, and walk some more.
17	Missile (once)	Will play the current sequence once, damage sprites in range, and die.
