Where is wrong? - 3417512908 - 12.06.2018

I try to make a random float

Код:

new Float:x, Float:y, Float:z;
	GetPlayerPos(playerid, x, y, z);
	new Float:rand = random(x+100) + x-100;//error
	new Float:rand2 = random(y+100) + y-100;//error
	SetPVarFloat(playerid,"diedx",rand);SetPVarFloat(playerid,"diedy",rand2);SetPVarFloat(playerid,"diedz",z);
	SetPVarInt(playerid,"diedv",GetPlayerVirtualWorld(playerid));
	SetPVarInt(playerid,"loading",1);

And pawno warnings:

2 Warnings.

Someone know why? I added "new Float:rand"
Isn`t "new rand"
But still give me warnings

random function accepts only integer as parameter and x/y is not. Use floatround

random take integer as arguemnt, not float so the compiler warns you about that.

Thank!It is useful!

I successfully compiled it

Код:

new Float:x, Float:y, Float:z;
	GetPlayerPos(playerid, x, y, z);
	new rand = random(floatround(x,floatround_round)+100) + floatround(x,floatround_round)-100;
	new rand2 = random(floatround(y,floatround_round)+100) + floatround(y,floatround_round)-100;
	SetPVarFloat(playerid,"diedx",rand);SetPVarFloat(playerid,"diedy",rand2);SetPVarFloat(playerid,"diedz",z);
	SetPVarInt(playerid,"diedv",GetPlayerVirtualWorld(playerid));
	SetPVarInt(playerid,"loading",1);

Wait, so how do you use it?

Re: Where is wrong? - NaS - 12.06.2018

That doesn't look very correct though. Even if it does work, it will not be a true randomized float (it will not be precise).

If you want a real random float you can do that by calculating a random integer between 0 and 1000, convert that number to float and divide it by 1000.0. You'll have a float from 0.0 to 0.999 and can use this as factor for the range you want to randomize.

For example, if you want a random float ranging from 0.0 to a given number (like random(), just as float):

Код:

forward Float:floatrandom(Float:val);
Float:floatrandom(Float:val)
{
return float(random(1000)) / 1000.0 * val;
}

Then you can use this function to calculate a true random float.

well it can never be 'truly' random but yea..
