this should work (just fill red parts)

typeset goto_x_y=...
typeset char='/|\-'
typeset -i tick=0
while [[ create your own condition ]] ;do
print -- "${goto_x_y}${char[${tick}]}"
tick=$tick+1
[[ $tick -gt 3 ]] && tick=0
done

Usually you should be able to use backspace instead of goto_x_y

I have not tested this but it should work.
