[SNIPPET][CLIENT] First Person View Exploring

[Borov]

So, I always wanted to try making GTA first person view, just for the heck of it. The code below can be inserted into your client side script, and to use it, you go in the game and use the command "/fps on" and "/fps off" to toggle the view. You can run around the map in first person view mode, and of course you'll be able to see your hands and feet. I'm not able to implement first person driving and targeting, due to certain limitations, but perhaps in later releases we can do that. also try ducking, and you'll see the camera lowers as well. Please feel free to expand on it so it becomes more fun.

EDIT: now you can see from the driver's view when you sit in a car. if it doesn't work, just hold aim button and release.

please report any problem or suggestions if you have tried it ^^

[Simbad de Zeeman]

Very usefull!

Can you post some screenshots? or video? because i cant run the script atm (@ work)

[Borov]

sorry don't have any... just try it when you get a chance. I can't wait to see how people may improve it

[paragon]

very interesting! Good work and thanks for sharing it ;D

[HITMANzz]

how can i put this on my server?

toggleCameraFixedModeEx()

and

setCameraPosition(x, y, z+0.7)

is deprecated, use setCameraMatrix() instead
