Unit change?

[BlackDrgn942]

how do i make it so that if somone buys a unit it removes the original 1 and changes it to the bought 1? Also can somone tell me how to make it so that a unit can only hold (i.e. only have 1-2 swords in inventory?

You could use a variable for this one. Make the standing unit into a variable. Then if another unit gets built, remove the unit stored in the variable and put the new one in its place. Variables are your friend . I am not sure WHAT IN hell you are talking about for the second one.
