shot-timing

Optimize shot timings in surviv.io

Program

The program takes the following inputs and outputs the optimal objective value and sequence of instructions:

• objective: minimize maximum time between adjacent shots, or time from first to last shot
• require shot at time zero: yes/no
• switch delay 1, switch delay 2
• mag size 1, mag size 2
• maximum slow penalty duration (0 for noslow, infinity for maxfiring)
• fire delay 1, fire delay 2 (not needed if maximum slow penalty duration is 0)

time from first to last shot resembles desync with require shot at time zero and underclock ("hard overclock") without.

maximum time between adjacent shots resembles what is described as "soft overclock" in the outdated terminology.

Algorithms

Minimize time from first to last shot

This is implemented with brute-force and memoization, which is effectively top-down dynamic programming.

At any time, there are only two decisions:

• which gun to shoot
• whether to wait out full switch delay or wait for next free switch

The state is ammo count 1, ammo count 2, current deploy group, and free switch timer.

Minimize maximum time between adjacent shots

This feature is not yet implemented.

Macro Generation

It is possible to take the output and create a macro to execute the instructions, but due to network latency, it is often better to tweak the timings manually.

This project has not yet implemented macro generation.
