This opcode sets a free hospital visit for the player. When enabled, if the player is wasted, he will not lose any weapons or cash after respawning. The free treatment works once only, so to allow free treatment again, you have to enable it through this opcode again. This opcode was never called in the [[Main.scm|original script]] of GTA III. The value set with this opcode is saved in [[Saves (GTA 3)#Block 16: Player Info|block 16 of the save file]] in GTA III, [[Saves (GTA VC)#Block 18: Player Info|block 18]] in Vice City, and [[Saves (GTA SA)#Block 15: Player Info|block 15]] in San Andreas.

GTA III Vice City San Andreas SET_FREE_HEALTH_CARE

Description
Enables a free hospital visit for the player
Syntax
0414: set_player [player handle] single_free_treatment [int]
Parameter
[player handle]
The handle of the player
[int]
0 = disable (default), 1 = enable
Native analog
SET_FREE_HEALTH_CARE

This opcode sets a free hospital visit for the player. When enabled, if the player is wasted, he will not lose any weapons or cash after respawning. The free treatment works once only, so to allow free treatment again, you have to enable it through this opcode again. This opcode was never called in the original script of GTA III. The value set with this opcode is saved in block 16 of the save file in GTA III, block 18 in Vice City, and block 15 in San Andreas.

Disassembled code

These are disassembled code for this opcode both from PC v1.0 US.
