its cool, ill just wait for 1.2 and the singleplayer commands for tht version so i can do the roll back for each time i wanna refill, i know i can just get my self the jar file for the version for the current SPC, but im at the pre release 8 thing now, ive built tons of cannons, the small ones is easy to fill but my mega cannons, u dun wanna see their size man, soundes perverted but u get my point

Pretty much. Problem is is that commands would really only work if a dispenser is defined with a fixed value that you can use, which is almost impossible without knowing the value of the block you create once you create it. The conveyors seem to offer a simple, engine based solution to manual refilling. Sorry if it wasn't what you were looking for.

thanks for the help but i dont wanna change my designs with this mod, u sent me this link cuz of the conveyor belts right? i though more like a command, imagine like:
"//fill dispenser 9x 64x fire charge"
like fill the dispenser with 9 stacks of 64x firecharge, shame there is no thing, i could use single player command to roll back maybe, like fill them all then roll back as a refill but i tried downloading that mod, doesnt work with me. probably did something wrong, ive never used mods, the tutorial said use modloader n just load and ur done, i did tht, but maybe i had newer version of minecraft? thanks for the help anyway

hentailord5Is there a mod for filling the dispensers with anything with a command? cuz im sick of filling my cannons, im a pro cannon builder, sick of filling them with stacks of fire balls over n over
