New Gun Code

Here is the extra code that goes into the gun to make it shoot. (See our tutorial "Detect Mouse Angle" for an explanation of all the code before this point. I used the "Detect Mouse Script" and just made some additions to it to make it a gun.)

Comment: the variable "shootchance" represents a percentage of 100. Since I use a random number, there is (in theory) a "shootchance" (pretend shootchance is set to 12) ... a 12 percent chance that the random number will be between 1 and 100. Since Random ACTUALLY returns a value between 0 and 99 I add +1.
Set Variable: "shootnow" = Random(100)+1
If (shootnow<=shootchance
Comment: keep increasing "shotname" so there are no shots with the same name ever. 

When duplicating movie clips (there is only one "shot", which is duplicated whenever we need another one to appear...) you must never have more than one item with the same "depth". Only one item can exist at one depth at one time. So I keep increasing the variable "shotname" and use it in naming the new shots so they have unique names. I used "1000" as a maximum because it is unlikely I will ever need to have 1000 shots on the screen at the same time so I can recycle the numbers. The reason I do this, is in a game, you will have many many items that you need to duplicate. Each one needs guaranteed unique "depths" for its own use. I set aside numbers for use by different movie clips in chunks of 500 or 1000 because that is easier to keep track of.
