Hello guys,
In my current project I am trying to implement a projectile shooting system that goes directly to the mouse position, however, because of reasons unknown to me, be it a problem in the code or, a problem in my sprite design - I cannot get it to go to the cursor. Which may or may not be causing other problems in the gameplay like the bullet seeming to bounce of the platform and also the bullet travelling along the platform and falling off instead of exploding like it’s supposed to :(.
I have included the weapons script and the movebullet script. I would also be willing to put all the source files in a Dropbox account to get a resolution to the problem.
As always any and all help is greatly appreciated!
Regards,
CK.

.
- I’ll modify my project and plug that code into it and see what happens. It would be good to fix this error that I’ve had for quite some time.
