i need help making the coffin stick to the ground when they rain down, i'm stuck and not sure how to code it

heres a screen shot

[Cyanide]

Rather than using destroyself in 902, use changestate to the landing one. Physics N, set velocity to 0 with velset, set Y pos to 0 with posset. Don't set the X values at all, you want it to stay in place. Only use the destroyself on the landing version, don't call the helper in its own state either, otherwise they'll just spawn over and over (and break things), you need to take that out. Short form

Dropping helper
changestate on ground level
new state for helper when it's landed
lock position with velset and posset
destroyself after X ticks.
