# Is it alright to downvote for a localized answer?

I saw this question:

How do I implement deceleration for the player character?

Asking how to implement this code In a short and elegant way:

 if speed > 0 then
speed = speed - 20 * dt
if speed < 0 then
speed = 0
end
end
if speed < 0 then
speed = speed + 20 * dt
if speed > 0 then
speed = 0
end
end


sign = (speed >= 0? 1 : -1);
speed -= sign * 20 * dt // 20 is the rate of deccelaration
if(sign != (speed >= 0? 1 : -1)) speed = 0;


It seems to meet the criteria presented by the question and it could be useful in platformers where you wish to deccelerate the chracter on the x- axis and control y-axis with gravity. It is also semantically identical to what the OP requested in the question.

Some people felt the answer was too localized to 1-d games and decided to downvote on that account.

Is that really a bad thing in answer, that it's written to best suit the question without adding more advance tecniques that were not required by the asker?
