i want some one to make a rock climbing gear mod so when you want to climb off a overhanger of a floating island it would be easy to get down and you can leave the rope that you use in the same spot so ypu can climb back up out of a sticky situation and away from mobs. there can be a climbing pick and grappling hooks and if you r holding on to the rope or useing a grapple hook you can click the center wheel and it will hold you in place while you use a mining pick to mine.
I'm in Norway at the moment and I was thinking of the exact same thing. I think if you generated a new block which held the same properties as a ladder (i.e took the existing java code for a ladder and a block such as cobblestone and added the two together) then you would be able to climb up rock faces. As for a rope, that might be harder to create due to the fact that you would have to program new physics and design in 3D the rope, which would have to move in a certain way. Also to make it more realistic, you would need items such as a spring-loaded camming device and belay device. If someone could figure out those items (rope, cam and belay) then we could all give steve bleeding virtual fingers and humongous calluses.
I know I'm 4 years late to the party, but a skill system would be nice. For starters, maybe an item that allows you to analyze the grade of certain rocks (coblestone as the lowest and climbable with no proficiency, smooth as highest), and then your skill proficiency corresponds to it. As in, there's a multiblock structure called a Bouldering Wall or something, and pretty much it has the same properties as the ladder, but for however long you spend going up and down on it, it upgrades your proficiency. Then, there are tools that could give you temporary proficiency boosts, similar to a potion of Fire Resistance temporarily makes you less vulnerable to fire damage. For example, a cam, chalk, or placeable climbing holds that would upgrade a surface. Bolts could be placed to make climbing easier the next time.
