Hi nooob,

You could probably just keep track of the total time and then mod it by the number of seconds you want between shots to check if the enemy should shoot:

The shootBullet method would simply create a new Bullet (assuming you have a Bullet class or something like that), or pull one from a pre-defined collection (if you have that instead).  Once the bullet is created, I imagine it would have it's own update method to handle its behavior.

I have a similar issue concerning the rate of fire. This is the code I use to determine how often an enemy shoots:

float thrustTimer;
float lastthrustTimer;
float thrustTimeSpan = 3.0f;  //declerations

thrustTimer = thrustTimeSpan;  //initialization

thrustTimer -= (float)gameTime.ElapsedRealTime.TotalSeconds;  //update

if ((thrustTimer - lastthrustTimer) < 0.0f)
{
if (thrustTimer < (thrustTimeSpan - 1.0f) && thrustTimer > 0.0f)
RocketShot(rocketList, enemyship);
}
lastthrustTimer = (int)thrustTimer;

This triggers the rocket shot between each second but it makes it too difficult for the player to shoot back so I want it to be between each 2 second interval, does anyone know how to do this? I got this method from the SpaceWar game so I don't really know how it works.
