03/19/2023, 2:57 AMUse mapandreas sir
Here is a code for you to base yourself on, just adapt it according to your preferences.
Copy code
cpp
#include <mapandreas>
stock IsPlayerNearFloor(playerid, Float:range) {
static Float:px, Float:py, Float:pz;
GetPlayerPos(playerid, px, py, pz);
MapAndreas_FindZ_For2DCoord(px, py, pz);
return IsPlayerInRangeOfPoint(playerid, range, px, py, pz);

03/19/2023, 2:59 AMColandreas would not be to detect collisions?

03/19/2023, 3:01 AMafaik it's more accurate than the mapandreas version

03/19/2023, 10:50 AMMapAndreas should be depracated IMO, it's pointless when there's CA

03/19/2023, 11:23 AMThe question was about height detection, not about collision detection ;-;

03/19/2023, 11:23 AMHeight detection is detected with CA

03/19/2023, 11:23 AMYou yourself used MapAndreas

03/19/2023, 11:24 AMIk, but you said it like it's for detecting collisions

03/19/2023, 11:24 AMYeah, your example will not work on custom created objects

03/19/2023, 11:25 AMMapAndreas looks for static San Andreas map height. CA for everything. Custom & static original map

03/20/2023, 9:27 AMnever used any of those libs
are they heavy?
just to understand @wonderful-traffic-197 @clever-air-16091 they do the same stuff, but ColAndreas detects when player is on custom objects, right?
and on col andreas its just change the function?
Copy code
c++
#include <colandreas>
stock IsPlayerNearFloor(playerid, Float:range) {
static Float:px, Float:py, Float:pz;
GetPlayerPos(playerid, px, py, pz);
CA_FindZ_For2DCoord(px, py, pz);
return IsPlayerInRangeOfPoint(playerid, range, px, py, pz);

03/20/2023, 9:29 AMis colandreas to collision? i saw a video...
could i use it to detect if player shots a vehicle or a wall before shot a player?
some players are using hacks to kill other players behind cars and walls

03/20/2023, 1:28 PMis it right?
Copy code
c++
#include <colandreas>
stock Float:GetDistanceBetweenPoints(Float:x1, Float:y1, Float:z1, Float:x2, Float:y2, Float:z2) {
return VectorSize(x1-x2, y1-y2, z1-z2);
}
stock Float:HeightFromFloor(playerid, Float:range) {
static Float:px, Float:py, Float:pz;
GetPlayerPos(playerid, px, py, pz);
static Float:fx, Float:fy, Float:fz;
CA_FindZ_For2DCoord(fx, fy, fz);
new Float:tempdist = GetDistanceBetweenPoints(px, py, pz, fx, fy, fz);
return tempdist;
}
