function add_exp

[jzy-chitong56]

the remove_exp no function call , so the exp_number only increase， once the upper limit is reached, there will be problems ？？

and even if call remove_exp , the exp_ancient and exp_creeps no reduction , they will still reach the upper limit

function remove_exp takes integer h returns nothing
  local integer i = h
  set exp_number = exp_number - 1
  loop
    exitwhen i  >= exp_number
    set exp_rp[i] = exp_rp[i + 1]
    set exp_unit[i] = exp_unit[i + 1]
    set exp_dist[i] = exp_dist[i + 1]
    set i = i + 1
  endloop
endfunction

function add_exp takes unit u, real dist, location ancient, group creeps returns nothing
  set exp_unit[exp_number] = u
  set exp_dist[exp_number] = dist
  set exp_ancient[exp_number] = ancient
  set exp_creeps[exp_number] = creeps
  set exp_number = exp_number + 1
endfunction
