New Version 2 out. Click hereI made a very simple fluid simulation in Game Maker:
Link to videoHere's the source:
http://anova.57o9.org/junk/fluid.gm81The controls are: click to place a wall block, right click to release water, Shift to erase whatever is currently under the mouse, Delete to erase everything, and Enter to make a water pump that continually releases water.
The cellular automata rules are very simple:
1. If space to left empty: move left
2. If space to right empty: move right
3. If both left and right spaces are empty: randomly move either left or right
4. If space below empty: move down
Here's the code I used to simulate the water physics:
if position_empty(x,y+6)
{
y = y + 6;
exit
}
if position_empty(x+6,y) and position_empty(x-6,y)
{
randrange = irandom_range(1,2);
if randrange = 1 {x += 6};
if randrange = 2 {x -= 6};
exit
}
if position_empty(x+6,y)
{
x += 6
exit
}
if position_empty(x-6,y)
{
x -= 6
exit
}I know I need to add a toolbar or a little box that shows the commands you can use in the next release. Besides this, any other suggestions or comments?

It's part of the physics lessons tutorials. And nice implementation! It seems you stumbled upon the same set of rules that I used! ^^
I don't know if I'll ever learn the language though.
