Easy Question?

I thought you wanted to detect inactivity because it confuses wave detection and looks like a bunch of 0.1 power waves are being fired. Gun heat tracking can help distinguishing inactivity from 0.1 power bullets being fired.

But trying to use wall hits to conceal a shot will make you bots movement quite predictable.

Analysing the last example, a bot with speed 4 which sets speed to 2 and shoots with power 1.0 will be shown in the opponents radar as a bot which decelerated from speed 4 to 0 and decreased 1.6 energy. Combat would detect a 1.0 power wave being fired (it ignores 0.6 energy drop whenever someone decelerates more than 2 in a single tick). But if it hits the wall with constant speed 2, then the 1.6 energy drop would be ambiguous. It could mean a 1.6 power bullet was fired and the bot stopped, or a wall hit with a 1.0 power bullet being fired. Currently, Combat would guess it is a 1.0 power bullet and if it was a 1.6 power bullet, dodging would be sub-optimal, but it would still react to the firing.

Another worse scenario: You hit the wall with constant speed 2. A false 0.6 power wave would be detected and gun heat tracking would kick in. Then, there would be a 12 tick window when a shot would go undetected. If it is a power 3.0 bullet, it would hit long after the 0.6 wave was dodged. Maybe I should disable gun heat tracking for 0.6 power bullets shot near walls.
