Thanks dkdoom for your help with this. I tried out your code.

in the cap below.

I am still having trouble with it. It seems to loop between just two targets. So if you or anyone else can take a look at to see whats wrong

edit

I forgot to to put down the controls.

arrow keys to move

space key to fire

C key to start tracking.

X and V keys to target next ship

.

I am making a space shootem up game and I would like to have a computer weapon tracking system with the option to go to next target.

I have the basic system down.

For Each Enemy
              PlayerShip: Pick closest to: Enemy.X , Enemy.Y
              AND  PlayerShip Has LOS to Enemy

                               System: Create object
                                         Redcross on layer 2
                                         at (0,0) from Enemy�s
                                         image point 1

                                                                                                                           PhaserFire: Set angle towards
                                              RedCross[/code:1jzj1zhd]

But I am not sure how to on a key press to pick another target. What would be the best way to do this?

I found two things to look at.

One is the minimap, in ver 098.9 the cap below works fine.

http://dl.getdropbox.com/u/1244375/SpaceShipDemo4.cap

In 0.99.3 the minimap has random graphic crap in it. I checked this on my home computer and work computer both do the same.

I found a work around for it, Just add a clear terrain first before you add the other minimap commands.

Two a sprite problem. It can also be seen in the above cap.

The Wall sprite (green) at the top also the one at the bottom of the play area. The Wall should be covered by the WallCover . This worked right in ver 098.9 But in the 0.99.3 the clear box part is still under the WallCover but the green part is offset above it.

In the Wall properties the Angle is set to -90.

I found if you set the Angle to 90 seems to fix this problem.

Nice demo, but something is fishing up the keys

Thanks andla,

Yes this little demo is far from done. I just got the basic engine done now. I have to get the HUD redone, right now it is set up for testing.

Get the scoring going and add lot more stuff to blow up

Also, you should check out the Custom collision mask for the astroids... with physics behavior you can draw a polygon around them to define a mask.

deadeye I can see that with something that stays the same size. but I am randomly changing the small astroids size. How would that work?

Yep deadeye your tips were right on target:)

The System compare was my problem. I knew it was something simple I was missing.

And thanks Davioware, now that I know that the System compare was my problem. I took out the extra code I put in tp track down the problem.

And if you or anyone else see anything else that could streamline the code let me know. Thats why I am doing this little demo project to learn how to code better in Constuct. And if you know any tips or tricks I like to see them.

Thanks deadeye for the tips. Ill give them a try and see how it goes.

Hello all,

I am building a simple Space Ship / Asteroid shootem up Demo to help me learn the Physics behavior. But I have run in to a problem. The Big Asteroids are not being killed off like they should. The Asteroids have ID and Damage Private variables. In the game when a Big Asteroid gets 100 Damage it is killed and 3 smaller Asteroids replace it. But it is not working right. In debug I see the Damage goes above 100 but does not kill the big Asteroid.

So if anyone can take a look and see whats wrong with it. I know it must be something simple I missed with picking a object.

Use the arrow keys to move ship

Use spacebar to shoot

Made with Costruct Ver 0.98.9

edit to add file.. It was a little to big to upload here.

What is the license like? Can creations be used in commercial games?

If you are just looking for a background image you can try this out "Universe Image Creator"

http://www.diardsoftware.com/index.html

I use this and it works very well. Its been around for a long time.

You can create REALISTIC images of space in just minutes. Create Nebula, Gas Clouds, Stars, Galaxies, Planets, and More....

*tunes in*

I am interested in how to create a realistic starfield as well (with the nebulae, gas clouds, distant galaxies and whatsnot to boot!). Particles would be the most suitable for this purpose, with some creative customization. Just for the background for space games.

Thanks stainsor for helping me out with the CAP

Now the hard part, making the card hand ranking system.
