Limiting number of shots at one time

Hello

I am making a game where the player shoots missiles at falling asteroids. I have it set up so when the player presses the spacebar a missile is fired.

I want to have it so the player can only have 3 missiles on the game screen at once.

I have set a local variable called "shot" on the missle object. I have the value of "shot" to increase vy 1 each time the space bar is pressed and the value "shot" decreases each time the missile goes beyond the playing are.

How do I check to see if the value of "shot" is less than three when pressing the space bar before the missile is created?

Thanks for any help.

On the press space bar event you add another condition next to it (blocks can contain multiple conditions) which is shot.variable < 3. This is found under the player object's conditions and then compare instance variable.

Thank you for your help.

This is what I have done but it is not working. Any suggestions?

LionZ thank you for your help.

I tried with a global variable and it still is not limiting the shots.

Here is my event sheet. Any suggestions?

On the action you need to add 1 to the global variable 'shot', you are increasing the wrong variable.

Thank you again.

I think this is correct but it is limiting the number of active shots to 5 instead of 3

You can just check this:

system -> compare two variables -> missile.count < 3

I don't think so? What were you using to verify that it's 5 shots. The variable can't go over 3.

I meant you don't even need the variable, user "compare two values", where the first value is missile.count (that's how many missile instances are currently existing in runtime).

Using a variable should also work, but you don't really need it. If you're using a variable, make sure you destroy the missiles in every event and reduce the variable number (outside of bounds, hitting something, or whatever other events you have for the missiles).

Thank you both-

I figured out the problem.

When I first was trying this out I made a local variable called "shot" with the missel.

I then made a global variable called shot but did not delete the local variable.

It works now plus I learned so additional skills.

Thanks again.
