I don't know what variables like:

Ship.x
and
Ship.y

are called, so I wasn't able to search it.

So here's my question:

how do you have arrays in types?

For example, if you were going to have multiple bullets in a 2D game on the screen, you would need the x,y,speed,damage, etc for each one. I want to use types with that, and arrays also. How would I do this?

Would you do it something like this?:



I doubt it, but I am just giving an example of what I am trying to do.

Thanks in advance

Global Dim Bullets(100) as BulletInfo

But I think there is a quirk that ARRAYS MIGHT be Global just because they are arrays - but - when you start having multiple source files in one project - you might feel like I do - "If I want it global - I'll tell it I want it global" ... I do this as habit regardless when declaring global arrays because this is how you must do it for NONE array things... like

Global Bullet as BulletInfo

Good Luck

Arrays are global unless made local by the user, heh.

Bullets.x(50)

Thank you for the help

UFO, if your using different types of Bullets, you can use two custom types, one for the BulletProfile, and one for individual Bullet information per Instance.



This would allow you to create several types of BulletProfiles in which your Bullets inherit their intial property settings from.

UFO - one more thing - Windows Killer said he recommends dynamic bullets versus having a fixed amount. (Dynamic means create them as you need them and destroy then when you're done).

I agree - however - lest not forget sometimes - limits are the right solution - sometimes having fixed arrays is the right thing to do. It really depends on many factors.

DO favor dynamic of "fixed length" things normally when designing stuff - but there are times when limits - whether as fixed arrays or a max number of dynamic ones at one time - are perfect - to limit "the amount of stuff flying around" for example - and other reasons you may be able to dream up.

GOOD DESIGN is extremely important - but so is getting the most you can out of your software! Sometimes this means doing unconventional things to get a desired result.

Remember - think outside the box - after all thinking in the box is like being in jail

Well, I ignored that part anyway.

I like having limited bullets because I find adding to arrays and stuff confusing. I don't plan on having an massive amount of bullets on the screen anyway.

Thanks though

Sorry for the double post.

Is is possible to have an array inside a type with an array?

Example:

Ship(x).Turretlocationx(y)

If so, how can I do it. I am having trouble getting it to work.

Thanks!

It's impossible. Go up to the top of Newcomer's Corner and click on Tutorials Thread. Inside you will find a tutorial on types, and it gives some work-arounds for your problem.

Darn. I've been thinking of a way to get around it, so it shouldn't be much of a problem.

Thanks though
