A great improvement on R0J0hound's idea could be adding another dimension to the array, which would store information about the material. This way we could have real "blood" which could have different colors. Interactions between materials would be easy this way, I suppose. Oh, if I could only code it, instead of "click-coding" it.

I know it. I tried it the way you describe, but I'm not really sure what to type in the brackets. Neither the point's name nor a number work.

Before moving, try checking if it doesn't overlap any other object, and if it does, check if that object is solid. You know the rest.

I have a sprite, I created some image points and named them. Then, I want another object to stick to one of the image points. How do I refer to the point's coordinates? Tried to do it by clicking the object in the window in the lower part of the screen, but it just doesn't see my image points.

Here's what I've got so far:

I've added a few more features since I've uploaded that but the file is on my other computer.

Wow, it's really creative. I see and understand how you did that, but what will happen when we want to add some interactions? This would probably require checking neighbors of every field in the array and would probably be very cpu-heavy.

Run Script - ObjectName.VariableName = x should help.

Set a private variable to your value.

Hello, this is my first post on this forum, but I have been watching it for some time. I started programming a "sand game", something like http://dan-ball.jp/en/javagame/dust/

Now I used a 3x3 px objects for various elements, with "physics" behavior, and in the events sheet I shaped various interactions between them, or some unique properties (like fire floating instead of falling down). It all works fine until I get a few dozens of particles on the layout, then it starts to freeze and/or crash, which is only to be expected. Seems I'll need to approach that problem at a different angle, and this is the moment when I ask for your help. How do you think I can solve that problem?
