• Description: Simulate pendulum motion

Summary
Hey guys, it's coollog. Haven't posted in a while, been busy with other stuff. But today, I felt like attempting a pendulum simulation, so I made this and it worked out pretty nicely. This simple script works pretty fast and can be used by anyone with half a coding brain, though it may not be completely accurate.
Also included are three useful scripts I've created called string_to_real (converts a string to a real number), get_real (gets user inputted number), and draw_arc (draws an arc fast and precise). I hope you can find these useful =P.

Screenshots
Here's a screenshot of the pendulum simulator in action (actually four):



Fun
Here are some configurations for different types of pendulums (post some of your own favorites too )

// A nice balloon
forcex = 0;
forcey = -10;
mass = 1;
coefrestore = 0.2;
radius = 200;

// Big 'n heavy
forcex = 0;
forcey = 5;
mass = 20;
coefrestore = 0.2;
radius = 400;

// Ring around the rosy
forcex = 0;
forcey = 0;
mass = 1;
coefrestore = 1;
radius = 200;

// It's a storm out here!
forcex = 5;
forcey = 3;
mass = 1;
coefrestore = 0.5;
radius = 300;

removed spoiler tags (AGAIN). dont mess with the template

This is a great little example. short and sweet. It's the first realistic pendulum that I saw that is easily graspable and portable to your game.

Code can be used to make a demolition ball or even floating balloons on a string. Good job

Thanks!

I have updated the OP with a gmk version of the source file so that ppl with older versions can also use this engine.
I've also added some quirky configurations for different effects you can attain with this engine. Try them out !

EDIT: I've made a cool little bobblehead dancer with this engine. Check it out at: http://gmc.yoyogames...howtopic=536281
