Learning Unity3D devlog - Day 05
Day 5 - Adding turret functionality
--
Today I have been hard at work at creating the turret projectiles, making them hit and then after 20 hits getting the enemy destroyed. I also added a range to the turrets, that only allows them to shoot a maximum of 30 units (1 block = 10 x 10 units). When the turrets are out of range, they also suppress fire.

Distance measurements
--
I created a function to check the distance to the enemy.  It creates a float called "distance" and assigns a Vector3.Distance to it. Afterward, it compares the distance with the range I defined (30 units) and if it is in range it starts shooting and orienting its turret head towards the enemy.

Bullets
--
The bullets are spawned by a particle system. The particle system spawning (emission) gets toggled by the logic mentioned above. When the particle hits the enemy, it sends out an "OnParticleCollision" call. The enemy then processes the call internally by subtracting some HP and if it's HP drops to 0, it destroys itself.

Thanks for reading!
