rand_number forage skill was created by JTP
Code:
if(rand_number(1,101) < GET_SKILL(ch, SKILL_FORAGE)) {


Is this what controls how often i will find something ?

If it is, then i found 1 food item in like 300 attempts...how can i improve the chance ?
I tried to use rand_number(1,2) still didnt help

Something else is affecting your chances of success. Please post the full function.

The number 101 is chosen so that whatever your practiced level of SKILL_FORAGE, that is the percentage of times you will succeed.

For reference, here is the implementation of the forage skill from Augmented Dimension (which is not currently run of course). You have my full permission to use it however you see fit. Hope it helps.
Code:
/* VNUMS of food objects that can be found on successful forage */ #define FORAGE_BERRY 20 #define FORAGE_ROOTS 21 #define FORAGE_GREENS 22 #define FORAGE_BARK 23 #define FORAGE_NUTS 24 ACMD(do_forage) { int move_cost = 10; int success; const obj_vnum forage_possibilities[] = { FORAGE_BERRY, FORAGE_ROOTS, FORAGE_GREENS, FORAGE_BARK, FORAGE_NUTS }; const int num_possibilities = sizeof(forage_possibilities)/sizeof(forage_possibilities[0]); int food = rand_number(0, num_possibilities - 1); if (GET_SKILL(ch, SKILL_FORAGE) < rand_number(1, 101)) success = FALSE; else success = TRUE; if (world[IN_ROOM(ch)].sector_type != SECT_FOREST) { send_to_char(ch, "You can only forage in the woods!\r\n"); return; } if (GET_MOVE(ch) < move_cost) { send_to_char(ch, "You are too tired to forage.\r\n"); return; } if (success) { struct obj_data *found = read_object(forage_possibilities[food], VIRTUAL); send_to_char(ch, "You forage and find a %s!\r\n", found->short_description); obj_to_char(found, ch); improve_skill(ch, SKILL_FORAGE); } else send_to_char(ch, "You forage for a while and find nothing.\r\n"); GET_MOVE(ch) -= move_cost; WAIT_STATE(ch, PULSE_VIOLENCE * 2); }

Code:
if(rand_number(1,101) < GET_SKILL(ch, SKILL_FORAGE)) { WAIT_STATE(ch, PULSE_VIOLENCE * 2); GET_MOVE(ch) -= (100 - GET_LEVEL(ch)); send_to_char(ch, "\r\nYou have no luck finding anything to eat.\r\n"); return; } else { item_no = foodItems[rand_number(1,sizeof foodItems/sizeof(int) - 1)]; WAIT_STATE( ch, PULSE_VIOLENCE * 2); /* Not really necessary */ GET_MOVE(ch) -= (150 - GET_LEVEL(ch)); item_found = read_object(item_no, VIRTUAL); obj_to_char(item_found, ch); sprintf(buf, "%sYou have found %s!\r\n", buf, item_found->short_description); send_to_char(ch, buf); act("$n has found something in his forage attempt.\r\n", FALSE, ch, 0, 0, TO_ROOM); return; } }

please use code tags. this is very difficult to read. also take a look at the edit i made up above. I posted some code as a reference

EDIT: I copied and pasted your code into an editor and formatted it for myself. The conclusion is there is way too much information missing for me to really help you. I can say the more effort you put into your question, the more help you will get.

If you would like me to help you debug your code, be sure to post both the entire relevant code section, as well as a sample of the test output from the MUD so I can see what is actually happening. Otherwise it is 100 times more difficult for me to figure what is going wrong than it would be if I had access to your code.

You have your if-statement checking for a less-than instead of greater-than... just change the '<' to '>'
