Well.. i've posted this back into gtaforums but seems that there arent many responses there and as for my first post in this community i'll ask this...

ok, the thing is, that San andreas returns incorrect values when I get the sine of a yaw (upwards/downwards) angle that is about 20 degrees before and after 90 or 270 (-90) degrees of yaw... like if it has the resulting values "locked" to a max angle... this only happens with yaws, sines and cosines work well on Z angles... and by the way, the yaw is calculated properly so getting the angle is not the problem...

hope you can help me! thanks!!!

Show us some code to go on

Ok, here is my "tester":

Get on a car, and lean it upwards/downwards something like 90 degrees... you'll notice that one of the lines points the wrong way...

For starters...

CODE

077D: 8@ = car 0@ x_angle

should be

CODE

077D: 8@ = car 0@ y_angle

Your sascm.ini is outdated. Update it here. Then fix those problems and try again.

I already knew that, getting the angle is not the problem, but getting the sine of the yaw yes...

[Deji]

What I don't get is why you even need sine/cosine for this. But if you want the first trail to follow the same 'yaw' as the other, just calculate the sine earlier and add it to the Z of that, too:

SANNY

0407: store_coords_to 1@ 2@ 3@ from_car 0@ with_offset -2.5 0.0 0.0
0407: store_coords_to 4@ 5@ 6@ from_car 0@ with_offset -2.5 1000.0 0.0
077D: 8@ = car 0@ x_angle
02F6: 11@ = sine 8@ // (float)
005B: 6@ += 11@ // (float)
06BC: create_M4_shoot_from 1@ 2@ 3@ target 4@ 5@ 6@ energy 0
0174: 7@ = car 0@ Z_angle
0013: 7@ *= -1.0
02F6: 9@ = sine 7@ // (float)
02F7: 10@ = cosine 7@ // (float)
0013: 9@ *= 1000.0
0013: 10@ *= 1000.0
0013: 11@ *= 1000.0
0407: store_coords_to 1@ 2@ 3@ from_car 0@ with_offset 2.5 0.0 0.0
0407: store_coords_to 4@ 5@ 6@ from_car 0@ with_offset 2.5 1000.0 0.0
005B: 4@ += 9@ // (float)
005B: 5@ += 10@ // (float)
005B: 6@ += 11@ // (float)
06BC: create_M4_shoot_from 1@ 2@ 3@ target 4@ 5@ 6@ energy 0

Now they are both side by side at all times. But you could also do this just using 0407, without calculating the sine values.

[hawk94]

ok, I want the sine/cosine of the Z angle and the sine of the yaw because I did a script that creates a "shoot" from a cannon attached to the front of the car, and I need those values to get the direction towards where the "bullet" will fly (adding sines/cosine to the actual position of the "bullet", repeteadly until it reaches its destination)... you can check my mod here: http://anmzgtasamods.blogspot.com/2011/11/...defensa_26.html just activate it with Tab+K and shoot with backspace... then lean the car some degrees (near 90 or -90) upwards/downwards and shoot again... you'll see that the bullet now doesnt follow the correct direction... same with missiles (shoot them with secondary fire)....

[Deji]

The code I posted works fine, though... Is your problem solved?

[hawk94]

hmmm... no, its not solved yet... the problem is that I can't use 0407, as the point I want to get is not always 1000 m at the Y offset from my car... thats why I need the sine and cosine of the Z angle and the sine of the yaw... as the object will move periodically towards that point, no matter where the car is facing, once the "rocket" has been shot... I still can use 0407 to get those sines and the cosine but only for that... I hope I didnt mess you up.. hehe... by the way... did you test my mod???

[Deji]

In my code, I didn't mess with 0407.

[hawk94]

no Im not saying that you messed in your code lol... by the way I think I've found what I was looking for here: wesser post

EDIT: I've solved this problem, thanks Deji!!!
In case you wonder: The thing was at the moment of getting the sines/cosines... the max distance (multiplier) must be multiplied by the cosine of the yaw, before affecting the sine and the cosine of the Z angle...
