Hello, I am making a shooter game and what has happened is that I made the gun and player successfully, but the gun is rotating around its own center point. But I want it to rotate around the player. How do I do that?

You need to rotate around the central axis (the player's position) by a certain angle and radius.

init = function()
  screen.setAlpha( 0.5 )
  screen.setColor("#FFFFFF")
  angle = 0
  player = object
    x = 0
    y = 0
    angle = 0
    arm = 50
    arm_x = 0
    arm_y = 0
    icon = 70
    icon_x = 0
    icon_y = 0  
  end
end

update = function()
  player.x += random.nextInt( 2 ) * 2 - 1
  player.y += random.nextInt( 2 ) * 2 - 1
  player.angle += 1
  player.arm_x = player.x + player.arm * sind( player.angle )
  player.arm_y = player.y + player.arm * cosd( player.angle )
  player.icon_x =  player.x + player.icon * sind( player.angle )
  player.icon_y =  player.y + player.icon * cosd( player.angle )  
end

draw = function()
  screen.clear()
  screen.drawRound( player.x, player.y, 20, 20 )
  screen.drawRound( player.arm_x, player.arm_y, 10, 10 )
  screen.drawLine( player.x, player.y, player.arm_x, player.arm_y)
  screen.setDrawRotation( -player.angle )
  screen.drawSprite("icon", player.icon_x, player.icon_y, 10, 10 )
end

can you please explain this code to me? I just wanted to understand what was going on

//-- Initialize function to set up initial parameters and variables
init = function()
  //-- Set screen transparency to 0.5 (50%)
  screen.setAlpha(0.5)
  //-- Set screen color to white
  screen.setColor("#FFFFFF")
  //-- Initialize angle variable to 0
  angle = 0
  //-- Initialize player object with properties
  player = object
    x = 0 //-- Initial x-coordinate of player
    y = 0 //-- Initial y-coordinate of player
    angle = 0 //-- Initial angle of player
    arm = 50 //-- Length of player's arm
    arm_x = 0 //-- Initial x-coordinate of arm
    arm_y = 0 //-- Initial y-coordinate of arm
    icon = 70 //-- Length of player's icon
    icon_x = 0 //-- Initial x-coordinate of icon
    icon_y = 0  //-- Initial y-coordinate of icon
  end
end

//-- Update function to handle changes to player's position and angle
update = function()
  //-- Randomly adjust player's x and y coordinates
  player.x = player.x + random.nextInt(2) * 2 - 1
  player.y = player.y + random.nextInt(2) * 2 - 1
  //-- Increment player's angle by 1 degree
  player.angle = player.angle + 1
  //-- Calculate new coordinates for arm based on player's angle
  player.arm_x = player.x + player.arm * sind(player.angle)
  player.arm_y = player.y + player.arm * cosd(player.angle)
  //-- Calculate new coordinates for icon based on player's angle
  player.icon_x = player.x + player.icon * sind(player.angle)
  player.icon_y = player.y + player.icon * cosd(player.angle)
end

//-- Draw function to render player and related elements on screen
draw = function()
  //-- Clear the screen
  screen.clear()
  //-- Draw a round shape representing the player
  screen.drawRound(player.x, player.y, 20, 20)
  //-- Draw a round shape representing the player's arm
  screen.drawRound(player.arm_x, player.arm_y, 10, 10)
  //-- Draw a line connecting player's position to the end of the arm
  screen.drawLine(player.x, player.y, player.arm_x, player.arm_y)
  //-- Set the draw rotation to the negative of player's angle
  screen.setDrawRotation(-player.angle)
  //-- Draw a sprite (icon) representing the player's icon
  screen.drawSprite("icon", player.icon_x, player.icon_y, 10, 10)
end

copy the code to a new project and run .

Code lines 35 and 36 are responsible for the rotation around the point where you are playing for the account value and the radius length.

Line 50 is responsible for providing the screen object with information that now all graphic elements are to be drawn at the angle we pass in the variable.

Line 52 is responsible for drawing the icon (weapon) at the screen location (coordinates) you calculated in lines 35 and 36.

so how do i make the weapon point to mouse pointer while maintaining an orbit around player?

you use atan2d()

//-- Initialize function to set up initial parameters and variables
init = function()
  //-- Set screen transparency to 0.5 (50%)
  screen.setAlpha(0.5)
  //-- Set screen color to white
  screen.setColor("#FFFFFF")
  //-- Initialize angle variable to 0
  angle = 0
  //-- Initialize player object with properties
  player = object
    x = 0 //-- Initial x-coordinate of player
    y = 0 //-- Initial y-coordinate of player
    angle = 0 //-- Initial angle of player
    arm = 50 //-- Length of player's arm
    arm_x = 0 //-- Initial x-coordinate of arm
    arm_y = 0 //-- Initial y-coordinate of arm
    icon = 70 //-- Length of player's icon
    icon_x = 0 //-- Initial x-coordinate of icon
    icon_y = 0  //-- Initial y-coordinate of icon
    icon_angle = 0
  end
end

//-- Update function to handle changes to player's position and angle
update = function()
  //-- Randomly adjust player's x and y coordinates
  player.x = player.x + random.nextInt(2) * 2 - 1
  player.y = player.y + random.nextInt(2) * 2 - 1
  //-- Increment player's angle by 1 degree
  player.angle = player.angle + 1
  //-- Calculate new coordinates for arm based on player's angle
  player.arm_x = player.x + player.arm * sind(player.angle)
  player.arm_y = player.y + player.arm * cosd(player.angle)
  //-- Calculate new coordinates for icon based on player's angle
  player.icon_x = player.x + player.icon * sind(player.angle)
  player.icon_y = player.y + player.icon * cosd(player.angle)
  
  player.icon_angle = atan2d( player.icon_x - mouse.x, player.icon_y - mouse.y )
end

//-- Draw function to render player and related elements on screen
draw = function()
  //-- Clear the screen
  screen.clear()
  screen.setDrawRotation( 0 )
  //-- Draw a round shape representing the player
  screen.drawRound(player.x, player.y, 20, 20)
  //-- Draw a round shape representing the player's arm
  screen.drawRound(player.arm_x, player.arm_y, 10, 10)
  //-- Draw a line connecting player's position to the end of the arm
  screen.drawLine(player.x, player.y, player.arm_x, player.arm_y)
  //-- Set the draw rotation to the negative of player's angle

  screen.drawRect( mouse.x, mouse.y, 10, 10, "red")
  screen.drawLine( mouse.x, mouse.y, player.icon_x, player.icon_y, "green")
  
  screen.setDrawRotation( -player.icon_angle )
  //-- Draw a sprite (icon) representing the player's icon
  screen.drawSprite("icon", player.icon_x, player.icon_y, 10, 50)
end

Thank you so much for the help!
