Robocraft 2 – Collision & Melee Damage Guide

Collision & Melee Damage

Collision Damage is applied differently to weapon damage. Melee Damage (from Chompers, Choppers, Flippers, Rammers, etc.) simply works by creating collision damage.

Impulse Magnitude

We use the Havok physics engine. When two objects collide in the physics engine the engine gives us an “Impulse Magnitude”. The impulse magnitude is based on the mass and velocities of the two objects that are colliding. We use this impulse magnitude to create damage to the connections between blocks.

Two objects colliding and creating an impulse

Collision Sphere Cast

At the point of collision, we generate a Sphere Cast. The centre of the sphere is positioned at the point of the collision. The radius of the sphere is determined by the impulse magnitude.

Using the sphere we find all connections [on enemy robocraft blocks] that lie within the radius and do damage to them.

The amount of damage is based on the impulse magnitude and the distance from the centre of the sphere. The damage applied falls off with distance with an exponential relationship.

Collision Sphere Damage

Damage from collisions ignores penetration resistance completely. All connections within the sphere are affected.

NB: Devs plan to improve the collision damage model to better account for the structure of robocraft so that structural integrity is better taken into account when collisions occur possibly via some kind of ‘damage routing’ system more akin to how it worked in RC1 for collision damage. We believe the relatively random destruction that occurs during melee combat results from the over simplified sphere cast system that we use.

I love games and I live games. Video games are my passion, my hobby and my job. My experience with games started back in 1994 with the Metal Mutant game on ZX Spectrum computer. And since then, I’ve been playing on anything from consoles, to mobile devices. My first official job in the game industry started back in 2005, and I'm still doing what I love to do.
