Sorry your browser is not supported!

I have started working through the beginners video tutorials, and one thing that has perplexed me is how sprites and images are referenced as integers. So for example to load an image and create a sprite from it the code would be:
loadimage(1, "player_ship.png")
CreateSprite(1, 1)

And then whenever I want to manipulate that sprite I have to reference it through the integer, eg:
SetSpritePosition(1, playerx, playery)

I don't understand how I could possibly keep track of that as a project got larger. In other languages I would give the sprite or object a name so if I have lots of sprites/objects I don't get lost (as easily). For example the code would look more like:
SetSpritePosition(oPlayer, oPlayer.x, oPlayer.y)


Is there some way to give the sprites etc readable names? Or is this how you have to approach development in AppGameKit?
My apologies if this is a very simple or often asked question!

I like to do that with an array of type like below which will load the images 1.png 2.png etc for all 10 and ssign them to image and sprite IDs

you could add random positioning in the above with the command
SetSpritePosition(mySprites[num].sprID,random(100,900),random(100,400))
for example
and to move

which moves all the sprites to the left by one pixel by getting there current location and subtracting 1

yasha,

it depends on your project and the # of sprites but you were already 1/2 way there when you wrote:



what i mean is, you've given the player sprite x & y positions variable names. instead, give the player sprite itself a variable name (and the image, too, if you need it). IE:


then to manipulate:

...for example.

basically, AppGameKit gives you the option of declaring the image, sprite, object #'s as you have (in this case "1" for image and sprite, above) or letting AppGameKit decide the object #'s while you reference them with variable "names" as you're wanting to do.

so, if you have 1 player sprite, see above. and, if you have a number of enemies, you could do similar with an array:


which you can reference similarly:

...for example.

beyond that, if you want to give your enemies additional characteristics (like defining their speed, rate of fire, etc), then you would want to use Types to define, organize and reference each, as fubar suggests. HERE is a basic example of that where i've given 20 different sprites a constant direction of travel using Types.

in other words, you don't (ever) have to reference the integer/object id itself.

hope that helps

Many thanks to both furbarpk and Virtual Nomad, that has cleared the issue up for me!
