Kisa swinging on a chain. The yellow dots are points, and the green lines are distance constraints (rules that say point A and B can't be more than X distance apart). Each pair of adjacent points in the chain are connected by a distance constraint, but this results in an undesired "stretchiness" - for reasons detailed in a previous devlog
. To fix this, I added a second distance constraint between each point in the rope and the rope's fixed point, which increases stability and allows the rope to swing smoothly and fluidly.
