Hello. In the game I'm working on (with someone from TIGSource), I'm wanting a character to be able to charge up a projectile, then shoot it at the increased speed.
As of now, the projectile (Arrow) has a private variable called 'Power'. I want, while the "Fire" control is held down and 'Power' is below 700, to increase the Power in increments of 175 every 200 milliseconds. Once the "Fire" control is released, the projectile is shot at the speed of 'Power' pixels per second.
Can anyone help? :<
