bar fight and weapon disable and enemy generator.

i need a script to disable weapons in a game but randomly drop items such as beer bottles and chair legs and also generate a new random enemy out of a selected few when one dies. also to make it so that enemys will atk each other. THe idea I had is when a beer botle or chair legs comes up, ypu atk it and then it goes away and gives you that item and then elts you have another turn to atk. Thank you very much. in advance and I really really need this
