Unity3d notes-tanks Tutorial Knowledge points Summary---How to fire bullets

Firing bullets requires

1\ Launch coordinates-----Transform firetransform

2\ Bullet-----Gameobject Shell

3\ Relative size Force-----float Maxforce

4\ Maximum launch time----float Maxchargingtime

5\ storage tank-------Slider Aimslider

6\ Related Sounds-----audiosource

Aimslider does not need to drag the bar and does not need a background

You can set Fillarea and fill to make the graphic effect.
