00E2

GET_PAD_STATE

---

Description

Gets the current button pressed

Syntax

00E2: get_player [int1] key [int2] state_to [var]

Parameter

[int1]

Pad, normally 0 for pad 1 (player 1), 1 for pad 2 (player 2)

[int2]

Button index

[var]

Variable to store the status

This opcode gets the status of the button. It returns a value between 0 and 255, 255 meaning the button is completely pressed down. For left and right sticks (buttons 0 to 3), it returns a value between -128 and 128, -128 meaning the stick is completely pressed one way and 128 meaning the stick is completely pressed the other way.

For Vice City

This opcode does not exist in Vice City but it is possible to retrieve the status of the button in the same manner as GTA III. 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, retrieves the value of the status of the button for pad 0.

:opcode_00E2
// 0@ - input param (button)
0@ *= 2  // offset in memory
0@ += 0x7DBCB0  // add to base memory location
05E0: 0@ = read_memory 0@ size 2 virtual_protect 1  // retrieve status of button
05F6: ret 1 0@

Use this line as a substitute for opcode 00E2. This can be placed anywhere within the external script:

05F5: call_scm_func @opcode_00E2 inputs 1 button [button] result [variable]

Note that this code's result does not distinguish between a dword (4 bytes) or a word (2 bytes), meaning that a pressed left or right stick can be interpreted as a dword value of 65408, which is a word value of -128 (0xFF80 in hex).
