Whenever I tried to use the slide attack to dispose of the fumpers (those spiky jumping bugs made of pure, undiluted evil), they’d jump back at me before reaching the ground, that’s how mean they are. ;D
So I went to data/object_prototypes/fumper.cfg and changed this line:
on_end_stand_anim="if(desired_facing != facing, animation('turn'), animation('start_jump'))
into:
Now they wait until they reach the ground (or, hopefully, the water or a pit) to attempt a jump.
