GTA III IS_BOAT


Description
Checks if the vehicle is a boat
Syntax
029C:   is [car handle] boat
Parameter
[car handle]
The handle of the vehicle

This conditional opcode returns true if the vehicle is of type boat. Legacy documentations had incorrectly described this opcode as "car stopped," which had remained uncorrected for a long time.

For Vice City

This opcode does not exist in Vice City but the game can recognize vehicles by type. The following example, using Sanny Builder with CLEO for Vice City in an external script (not the main one) and tested on US v1.0, should work similarly to this opcode. Place this at the end of the file:

:opcode_029C
05E7: [email protected] = car [email protected] struct
[email protected] += 0x29C  // vehicle type offset
05E0: [email protected] = read_memory [email protected] size 1 virtual_protect 0
    [email protected] == 1  // is type boat
05F6: ret 0

Use this line as a substitute for opcode 029C. This can be placed anywhere within the external script as a conditional statement:

// ...
if
    05F5: call_scm_func @opcode_029C inputs 1 car_handle [car handle]
then
    // [RETURNED TRUE]
else
    // [RETURNED FALSE]
end
// ...
