***************************

Update:

Working on descriptions, if you can leave a comment with a 2-3 sentence description of what your example(s) do. I will add to the table below.

Thanks!

***************************

Thanks for showing interest in this project.

It will be a collection of 100 ways to improve a GMS2 game, either as GML code or a script.

Basically any coding you think is cool, or code that does a great graphical effects.

It can include pretty much anything that someone could add to an existing project.

Ideally you will submit in multiples of 5, so could contribute 5 or 10, etc, but just 1 is OK.

Payment will be made via PayPal, upon publication of the book and every 3 months when I receive payment. Upon publication you will also receive payment of any pre-orders made. Payment will be a share of 50% of the net revenue received from ebook and paperback sales, depending on how many examples you submit.

Make your suggestions in the comments below, and I’ll add to list.

Once I have a few scripts together, I’ll upload a ZIP of the project files you contributors can download and look at, and make any suggestions for improvement.

All contributors will have their name in the book.

Use the comments at the bottom of the page to add what topics you would like to work on.

Please submit as a project file, showing the code / script / effect in action. You can email them to me at: gamemakerbook@gmail.com

    Hey Ben, I have some ideas I can work on already:

    -RPG Style text (show whole string over time, with sound effect)
    -Crafting via Recipes
    -Item Throb Effect
    -Screen Shake
    -Item Glow effect
    -Item Reward Effect
    -Fade In/Out on Room Transition
    -Save/Load ini file system

  2. David says:

    At the moment ideas I can think of are:
    -Bezier curve paths
    -Targetted parabolic paths
    -Character Customization
    -Custom pathfinding
    -Ropes between objects
    I’ll hope to send the first few in the next week.

  3. Quadier says:

    10 Ideas I would like to cover.
    -Networking
    -Procedural Generation
    -Optimizations
    -Platforming
    -Platfomer AI
    -TopDown AI
    -Delta Timing
    -Development Console

  4. Cloaked Games says:

    Here are a few things I was thinking of doing. Also Quadier already posted two of the ones I had thought of a while ago, lol.

    -Enemy/player wounded effect. (Blinking)
    -Weighted loot tables.
    -RPG style damage calculation.
    -Doors for going in between two rooms. (Basically, how to link two rooms together in an easy way).
    -Popup text bubbles. (Not dialogue boxes, I’m talking about like, “Hello” when you walk past).

    Also, one question:
    -Does RPG Style text include a typewriter effect? If not I’ll do that too as a separate thing.

    I’ll get around to these in a few weeks. I have school testing to finish first.

  5. Zack says:

    5 ideas I can cover, based off videos on my YouTube channel, The Step Event:
    – Tweens and Easings
    – Button effects using elasticity and springs (Hooke’s Law [https://www.youtube.com/watch?v=vewwP8Od_7s])
    – 2D Dynamic Water (builds off elasticity concepts from Buttons [https://www.youtube.com/watch?v=LG3wocqjC-0])
    – Sunburst effect (lengthdir_x and lengthdir_y primer [https://www.youtube.com/watch?v=Xa6fgYUG1gA])
    – Fake 3D sprite spinning (sin/cosine primer [https://www.youtube.com/watch?v=fJxZyHArSKA])

    – Zack

  6. Rob says:

    -Highlight text when mouse Hovers

  7. Rob says:

    -Tooltip Text Popup!

  8. Rob says:

    -Interesting Health Bars

  9. Rob says:

    My next 5 will be:

    -Autonomous Ship Turrets
    -Interesting Buttons
    -Cool Intro/Chapter Text
    -Making a tiled World Map via code
    -Screen-Flash Damage Indicator

  10. Joe Ellis says:

    Hi, I’ve currently only got 1 project, but am hoping to come up with another 4.
    The one I’ve got is:
    Platform collisions with slopes & moving platforms.

    It basically consists of a player object, blocks, slopes and platforms (that move).
    And 5 concise scripts:

    collision_step (put this in the step event of any object, and it will perform the following (if needed))

    collision_solid

    collision_slopes

    collision_platforms

    and collision_unstick, which stops any errors occurring or getting stuck.

    Let me know if someone has already done one for this.

    1. Joe Ellis says:

      Came up with a better name for it:

      Platform & Slope Collisions

  11. Joe Ellis says:

    I would like to add:

    Topdown vehicle physics

    3D water with normal maps, refraction & reflection. (Possibly could be too advanced for ways to improve your game, but let me know)

    2d destructible terrain, but Ben has already put this. so it probably repeats what he’s done, not sure cus my version works per pixel, like on worms 1, so could be different and worth having both

    Maybe 3d shader materials, a collection of shaders rendering all the standard things like normal mapping, specular, cubemapping, erm, but I’m not sure if you want stuff like this to be in the book cus 3d stuff is abit “out there” for gamemaker..

    1 last thing, hue shifting, saturation, color limiting, etc. that could be a collection of shaders.

    Just let me know, I can put these things together if you want

  12. Rob says:

    -Zooming in/out on a map
    -knockback effect

    This should take my total to 15
