A problem with angles and coords

[fireguy109]

I am working on a first person mod and I need to point the camera at a point exactly 200 units away from the player's car. I am using basic trig.

When the script is activated, the camera just points east (90 degrees) and does not rotate when the car does (it moves N/S/E/W though, without turning, like moving a tripod but not turning it). It appears this is the default for cameras, as when the camera is not pointing anywhere it points east. I would really like to find out a way to make this work right.

 

Did I mess up my sine and cosine or is it something else?

 

EDIT: I can use GTA III opcodes only, and this is SCM not CLEO.

Well, according to GTAG, you've got 02F9 and 02F8 mixed up.

[fireguy109]

But all that does is get the x and y angles for the camera, so if the car flips the camera flips too, etc.

 

Fixed that but the problem still appears.

Try converting the angles to radians.

[fireguy109]

Nope, didn't work.

 

EDIT:

 

 

0160: point_camera $XPOS $YPOS $ZPOS 2

 

I'm playing around with different values for where 2 is, in the hopes of finding a solution. Using this as a guide-

No luck so far with anything other than 1/2, and those don't fix it.

I was hoping to make my own.

 

I guess I'll just open it up and see how they did it.

Just wanted to show that there is an another way to do it.
