setting a car's x angle

[yair1221]

im missing that opcode in my sacm.ini and opcodes.txt

can anyone give it to me?

ive tried updating to the latest ini but its still not there...

[TheSiggi]

Its missing, because it doesn't exist

 

try this:

 

 

0A97: $CarStruct = car $MyCar struct+20 = [byte] Contains a pointer to the rotation/position matrix (84 bytes):   * +0 = [float] X-axis Rotation (Grad)   * +20 = [float] Y-axis Rotation (Looking)

 

 

 

[yair1221]

sorry, i didnt really understand, is that a memory address?

if it is, then whats the address?

[Nahiyan]

 

0A97: [email protected] = car [email protected] struct0A8C: write_memory [email protected] size 1 value 360.0 virtual_protect 0

 

 

Not sure about that size tho.

 

[TheSiggi]

eh?

0a97 gives you the pointer to the car you passed to the opcode, so you still need to add the 20

+20 = [byte]

Contains a pointer to the rotation/position matrix (84 bytes)

 

 

 

and then add what you want to it:

 

   * +0 = [float] X-axis Rotation (Grad)   * +4 = [float] Y-axis Rotation (Grad)   * +8 = [float] Z-axis Rotation (Grad)   * +16 = [float] X-axis Rotation (Looking)   * +20 = [float] Y-axis Rotation (Looking)   * +24 = [float] Z-axis Rotation (Looking)   * +48 = [float] X-axis Position   * +52 = [float] Y-axis Position   * +56 = [float] Z-axis Position

 

the only relevant slots which reading out would make sense are

 

+4 = [float] Y-axis Rotation (Grad)

 

and

 

+16 = [float] X-axis Rotation (Looking)

 

 

so:

 

 

{$CLEO}0000:const   _myAngle = 180.0 // float   _size = 1 // byte endwhile true   wait 10   if   0256:   player $PLAYER_CHAR defined    then       if and       03EE:   player $PLAYER_CHAR controllable        00DF:   actor $PLAYER_ACTOR driving        then           if            0AB0:  key_pressed 0x09 //--------------------------------- TAB           then               03C0: [email protected] = actor $PLAYER_ACTOR car               0A97: [email protected] = car [email protected] struct               [email protected] += 20 // +20 = [byte] Contains a pointer to the rotation/position matrix               // read directly or add                // [email protected] += 16 //+16 = [float] X-axis Rotation (Looking)               0A8C: write_memory [email protected] size _size value _myAngle virtual_protect 0               Car.RemoveReferences([email protected])               break           end       end   endend0000:0000:0A93: end_custom_thread

 

 

because i don't have any compiler I can't garantee any results

 

cheers

crashes

here is what i did:

 

03c0: [email protected] $PLAYER_ACTOR08E6: set_plane [email protected] landing_gear 1 //TABif0ab0: 9then0A97: [email protected] = car [email protected] [email protected] += [email protected] += 40A8C: write_memory [email protected] size 1 value 180.0 virtual_protect 0end

 

[BnB]

You have to read memory after [email protected] += 20!

03c0: [email protected] $PLAYER_ACTOR08E6: set_plane [email protected] landing_gear 1 //TABif0ab0: 9then0A97: [email protected] = car [email protected] [email protected] += 200A8D: [email protected] = read_memory [email protected] size 1 virtual_protect [email protected] += 40A8C: write_memory [email protected] size 1 value 180.0 virtual_protect 0end

 

 

something like that?

[Adler]

Floats are 4 bytes; when reading/writing floats you should set the size to 4.

03c0: [email protected] $PLAYER_ACTOR08E6: set_plane [email protected] landing_gear 1 //TABif0ab0: 9then0A97: [email protected] = car [email protected] [email protected] += 200A8D: [email protected] = read_memory [email protected] size 4 virtual_protect [email protected] += 40A8C: write_memory [email protected] size 4 value 180.0 virtual_protect 0end

 

 

but, this should work?

[Nahiyan]

Yeah it will work!

[yair1221]

hmmm...it DOES change the angle, but my car gets wild and starts spinning all around...
