In this demo you can find 5 types of targeting system (including camera targeting). 1. Direct: Like look_at() but uses positive z-axis 2. Smooth-Follow: Non linear, Follows the target, no lock on 3. Smooth-Lock: Non linear, locks on at end, not good for mecha feel 4. Constant-Static: Linear, simpler code, for static target/player, good for static mechanical stuff 5. Constant-Moving: Linear, more complex code, works with moving target/player, good for moving mecha
