Mips x32 simple array problem....

[basketball8533]

Hey Everybody... im writing this code for one of my assignments and i need to have an array of size 128 which i do by

drops: .space 128

so that i can take a random number,
use that as the index and store a number 0-8 to it.....

so that in the end when i hit that number it will print out a number 0-8

for example.... say the random number was 32 and i was on the first iteration of the loop it would store 0 in the 32nd spot of the array if i was in the 2 iteration of the array... it would store 1 in the random number eg 92..spot

here is my code:

I first made everything in my array -1 so that i can test to see if something was in it...


storeArray:

li $t1, 0 #counter
li $t2, 0
loopStoreRandom:
la $t6, drops
bgt $t2, 128, exit
move $a0, $s5 # send x
jal getDrop
move $t2, $v0

add $t6, $t6, $t2 #random + the whole
lb $t3, ($t6)


bne $t3, -1, loopStoreRandom

sb $t1, ($t6)

addi $t1, $t1, 1
addi $t2, $t2, 1
beq $t1, 8, sub8
j loopStoreRandom



sub8:
addi $t1, $t1, -8
j loopStoreRandom



As you see i wish there was something that i could to just be like sb $t1, $t2($t6) but i cant...

whenever i test the code in exit... ex


exit:
lb $t5, 2($t6)
move $a0, $t5
li $v0, 1
syscall
li $v0, 10
syscall


It prints -1 everytime... and thats not what i want...
