Tank game updates:
- Bullet and Landmine classes no longer take width, height, life (bullet only) or pipeAngle (bullet only) in the constructor because these should always be the same.
- Pressing Shift and T at the same time now kills all currently alive enemies. Useful when testing some stuff like landmines while enemies constantly shoot at them and run over them. :)
- Landmines now have a timer of 15 seconds before they start their initial countdown. This means that after 15 seconds they will start the last 'type' of countdown where they turn red and back to yellow and the switching time between the two takes shorter and shorter till it's eventually 10 ms and then it explodes. The same effect happens when walking over a landmine, however it then starts counting down immidiately rather than waiting 15 seconds.
- Landmines won't detect any collision up till three seconds after they were spawned.
- Shooting landmines no longer results into players being unable to shoot any more bullets.
- Update TODO.txt.
