## turret system
### design
**upgrade graph:**
laser -> (heavy laser -> minigun) or (sniper -> railgun)
shotgun -> cannon -> tesla
plastic -> heavy plastic -> plasma plastic
slower -> (heavy slower -> final slower) or (stopper -> heavy stopper)
T generator -> kad generator -> s generator

### placement
- **only place when not ovelapping**
- **ghost cursor**
- **buy spending resources**
- shader to ghost cursor
### targeting
- **check visible**
- **check range**
- target selection
- **first**
- last
- strongest
- weakest
- closest
- further away
- least turning
- densest
- precalculate valid path nodes
### shooting
- **spread**
- _projectiles per shot_
- projectile logic
- **bullet**
- _ray_
- **plastic**
- projectile stats
- projectile models
- bullet
- ray
- plastic
- bullet bounce
- plastic bounce
- projectile fx
- trails
- explosions
- shooting particles
### economy
- **resources on enemy hit**
- generators make resources at end of wave
### upgrades
- _turrets can be upgraded_
- _only if can afford T_
