Drag Finger To Aim,Release To Shoot

Hye there i m making a simple Shooting Game but its not like FPS(First Person) shooting game..

it is simple 2d (Mobile game) where if we touch anywhere on screen player aim at that point and a Aiming arrow is also appear and when we release it shoots the bullet....

i know I can make that with the help of OnPointerDown , OnDrag , OnPointerUp function but because i m beginer i cant code that properly i tried but failed every time....
and one more thing bullet has rigidbody so we only have to addfore in the direction of pointer released plz helpme out.....

if there is any Video Tutorial availabe similar to my Problem then plz send me link...

i will be thankfull n appricate u in advance for my help
u can Better understand with photos that i attached what i m trying to do....

 

1. when the user presses the screen, store the position firstPressLocation
2. when the user releases the finger store lastPressLocation and do the following:

- calculate the velocity by vel = (lastPressLocation-firstPressLocation).normalized * speed

Improving it so a small drag fires less would be to also multiply it by screen height or other fixed factor. Personally, I use units and never go into screen space so I would have converted the touch into world space first for resolution independence.

But good luck. It's a trivial problem.

 

for u its trivial :-(
i m beginer....
in unity and in coding tooo :-(
is there any video tutorial available?

hye eses i saw that videos u dont got my point :-(

 

sorry to disappoint you, but you asked twice about video tutorial - nowhere did you mention that you have already watched that very same official tutorial video. So I provided it. I don't have any other tutorial for you however.

RajRajRaj: I remember reading this, I fear it's bit complicated, however, do you actually need full path?

http://answers.unity3d.com/questions/377334/how-to-move-object-parabolic-projectile-path.html

Maybe just show direction and length of pull, that might be enough for player, and way easier to code?

 

yup i need...

i appricate ur help but as i told before i m beginer and learn thorungh video tutorials...

anyways thanx 4 ur presious time

 

RajRajRaj: NP, and if you come up with proper solution please do share it here.
