old [EngiN33R] Player Collision

This is an extremely simple and short script that makes players unable to pass through each other. It was also designed as an educational tool to demonstrate some of the mathematics commonly used in CS2D scripts. The entire script is 16 lines long and provided in the description below because of its small size. Be aware that this collision mechanism may be slightly confusing and may not work ideally for players with a high latency.

I welcome any and all questions regarding how it works, and any improvements to it as well - bear in mind, however, that this is not the end-all solution, but a simple script that enables basic collision functionality.

@user Pagyra: Here, I optimized the code for you:

1
addhook("move", "collisionThink") function collisionThink(ply, x, y) for _, ply2 in pairs(player(0, "table")) do if (ply ~= ply2 and player(ply2, "health") > 0) then local x2, y2 = player(ply2, "x"), player(ply2, "y"); local d = math.sqrt((x2-x)^2 + (y2-y)^2); if (d < 30) then local a = -(math.atan2(x2-x,y2-y)+math.pi/2)%(2*math.pi); local nx, ny = x2 + math.cos(a)*30, y2 + math.sin(a)*30; if (tile(math.floor(nx/32), math.floor(ny/32), "walkable")) then parse("setpos " .. ply .. " " .. nx .. " " .. ny); end end end end end

I even added semi-colons so Lua can read it

seconds faster! (actual 100% legit full proof speed test)

It is inefficient, there is no optimization with separation space for parts. But the fact that there is nothing similar here, it is good.

Would be nice if there was a option to push the players if they block you.

collision engine



Simple yet useful. With that said, this is just a guess but wouldn't it lag with many players?

In my humble opinion, this feature should come by default amongst with a global server command sv_plcollision to enable / disable the solid state collision between players.

Otherwise, may can you implement this as a small improvement? Would be appreciated.
