Camera weapon opcodes

[james227uk]

Can anyone possibly tell me how this opcode works?

 

 

068E: get_camera_target_point_to [email protected] [email protected] [email protected]

 

 

I tried it numerous times, but it wont get the actual position the camera (weapon) is pointing at

It is used in the low rider mission and Cesar and Catalyst among others to get and reposition the camera.

 

For example, in the swimming mission for Wuzi Mu it is used like this:

 

 

:WUZI2_6313068D: get_camera_position_to [email protected] [email protected] [email protected] 068E: get_camera_target_point_to [email protected] [email protected] [email protected] if   not Car.Wrecked([email protected])else_jump @WUZI2_6365 Car.StorePos([email protected], $TEMPVAR_FLOAT_1, $TEMPVAR_FLOAT_2, $TEMPVAR_FLOAT_3):WUZI2_63650925: restore_camera_to_user_defined 092F: lock_camera_target_point 1 0930: lock_camera_position 1 0920: point_camera [email protected] [email protected] [email protected] transverse_to $TEMPVAR_FLOAT_1 $TEMPVAR_FLOAT_2 $TEMPVAR_FLOAT_3 time 3500 mode 1 0936: set_camera [email protected] [email protected] [email protected] position_to [email protected] [email protected] [email protected] time 3500 drop_mode 1 

 

 

From what I can understand;

• variables 51 to 53 are the x, y, z of the cameras position
• (I believe) 54 - 56 are the x, y, z rotation of the camera or something to that effect
• WUZI2_6365 restores the cam and locks it on a target
• Opcode 0920 is used to pan the camera across to something else
• Then the variables guide it back to origin using Opcode 0936

In order to actually "know" x, y, z position the camera is pointing at you would need a distance variable which is not here. For example:

 

If I am standing at position x, y, z and I know I am pointing the camera north down at a 45 degree angle looking at a cardboard box, I would need at least one more variable the distance to the object. Then you get into all that math about tangent of triangles.

 

In short, I don't think Opcode 068E was what you were seeking.

This opcode doesn't get where your weapon is aiming at. It gets point that is a few centimeters in the front of camera. By using this with no_obstacles opcode you can find the actual position of the point the camera is looking at.

I know it's a big UP, but I am in the same interogation.

I am trying to make a heli camera ( like IRL camera ).
I managed to attach the camera above the heli, I am in free look mode (mouse look)

But I would like to make a "track" mod in which the camera stay locks pointing at a specified coordinates.


Opcode no_obstacle, can you tell me more aobut it please ?

 

Thanks
