Coding Practices: Optimizations

This is a list of current coding optimizations and "hacks" I use in LSL and in examples They are all tested personally

1. when testing a function that returns -1 on NOT_FOUND
   • use (~test_function) -[eg. if (~llSubStringIndex( "abcdef", "t")){
   • instead of (test_function != -1) -[eg. if (llSubStringIndex( "abcdef", "t") != -1){
   • because it runs faster -[(!~test_function) also works for FOUND
2. when testing a list for a specific single entry
   • use llListFindList( vLstBase, (list)"test" )
   • instead of llListFindList( vLstBase, ["test"] )
   • because it runs faster and smaller compiled -[eg. if (llListFindList( vLstBase, (list)"test" )){
3. when incrementing counters or variables
   • use (++vIntCount)
   • instead of (vIntCount++) or (vIntCount += 1) or (vIntCount = vIntCount + 1)
   • because it runs faster
4. When testing if/else conditions place true statement first if possible
   • use (test) or (test == value)
   • instead of (!test) or (test != value)
   • because it's clearer & faster
