Make this code shorter?

By Jochends, with no replies.

Hi, I am making a scrolling platform game, and the grass that my character is standing on needs to be on the bottom of the ground for a while, when scrolling and i used the following simple code <Code Omitted> As you can see the Y-coordinate is always the same and he adds up every 128 pixels on the X-coördinate ( 193 + 128 = 321 and 321 + 128 = 449 and 449 + 128 = 577 and so on ). Is their an easier code to just let my object let say multiply itself on that Y-coördinatie with 128 pixels for 10 times or so? something with a counter? I don't find the proper code for that

It is then offsetted for the fact that it spawns in the center of the platform (+70). The initial -70 I don't understand though.

The center of the platform has nothing to do with it. By center, you are talking horizontally. These adjustments are on 'getY()'. The (-70) and (+70) are in 'setLocation' calls adjusting the vertical location of the platform. The two 'setLocation' statements offset each other so not change in location is the end result. The reason for moving the platform up is that the Alien objects were placed 70 pixels above the platform and we neede

Another couple of minor improvements: editing a discussion post (successfully) now returns you to the bottom of the last page of the topic instead of the first page, and a '#' link has been added on all discussion posts to make it easier to obtain a URL for linking directly to a post.

The code I have tried is this < Code Omitted > then it says "cannot find symbol - variable.

I presume 'bullet' is highlighted. Do you declare the 'bullet' variable anywhere? If so, where? How? Does it currently reference an Actor object? Show more code.

What is wrong with this script?

Last reply by danpost, over 9 years ago:

Move line 24 down to line 32 so that you only add a 'two' or 'three' when the value of 'wormsEaten' changes.

Let each scoreboard show the value of one actor. So at the end of the game, each actor could pass its 'score' to a scoreboard. You have to be more specific to get the help which you need.

Have an Actor point towards direction (left, right, up, down)

The easiest way would probably be this: <Code Omitted>

textbox input

You probably need to create a subclass of Actor for the object; create the base image in the constructor; add a field for the text; create a method that create an image of the text, draws it on the base image and sets it to the actor; add a boolean field to represent focus state; add code to the act method to check for focus, and if focused, check keyboard input and adjust the text and update the image as needed.
