9 years ago - Localize all standard lua and Spring API functions.
- The or-operator is faster than a nil-check. Use it!
- Don't use pairs() or ipairs() in critical code! Try to save the table-size somewhere and use for i=1,x do!
- Buffering can speed up table item access. 'local y=a[n]; y.x=y.x+1': 1.140 (100%)
- Don't use table.insert!!! Try to save the table-size somewhere and use a[count+1]=x!
