Verlet integration for GMS2.3+

Thank you! I think I added an option to change the 'stiffness' of the verlet system so it doesn't stretch so much. You should be able to manipulate it either in the rope function or the function which sets up the verlet system. But do note that increasing the stiffness draws a lot of performance, as this basically multiplies how many times per frame the whole physics simulation gets updated.

Thank you :) The verlet system is drawn using the VerletSystem() struct's Draw() function. The depth would be equal to the object which calls the Draw() function. By changing either that object's layer, or where you call the Draw() function (depending on your case), you can control the depth at which it is drawn. There is however no functionality to sort different verlet groups within the same verlet system after they are created. Groups within a system will be drawn in the order in which you added them with the VerletGroupCreateRope() or other functions. If you need to change them dynamically, you could either create multiple verlet systems, or write a new function inside the VerletSystem() constructor, which rearanges the "verletGroups" ds_list. Hope this helps!
