GetPointFromDistanceRotation

From Multi Theft Auto: Wiki

This function takes a set of XY coordinates, a distance and a rotation argument. It returns XY coordinates of the point that is the given distance away from the given point, in the given direction.

Syntax

float, float getPointFromDistanceRotation(float x, float y, float dist, float angle)

Required Arguments

• x: The X coordinate of the starting point.
• y: The Y coordinate of the starting point.
• dist: The distance from the starting point to the target point.
• angle: The direction from the starting point to the target point.

Code

function getPointFromDistanceRotation(x, y, dist, angle)
 
    local a = math.rad(90 - angle);
 
    local dx = math.cos(a) * dist;
    local dy = math.sin(a) * dist;
 
    return x+dx, y+dy;
 
end

Example

addCommandHandler("surround",
function (player)
 
  local x,y,z = getElementPosition(player);
 
  for i=1, 8 do
    local newX, newY = getPointFromDistanceRotation(x, y, 2, 360 * (i/8));
    createPed(10, newX, newY, z)
  end
 
end
);
