Hi awesome reader!<\/p>\n
In our past tutorial \u201cHow to Draw Line\u201d we discussed about drawing a line in the game by mouse
\ninteraction. But sometimes we need to draw a line that collides with our game objects in 2D mode.
\nSo we need to add physics to our line drawing system, then we are going to learn you how to do it.<\/p>\n
Getting Started<\/strong> Now attach the DrawLine2D \u200bscript to the Created Empty Game Object and Play the game. <\/p>\n Explanation<\/strong> Try to make a game with this awesome line drawing script!<\/p>\n Resources<\/strong> <\/p>\n
\n– Create or Open an Empty Scene
\n– Change Camera projection to Orthographic, otherwise it won\u2019t work.
\n– Create a Game Object with Physics Enabled (Add Sprite, Collider and Rigidbody2D)
\n– Create a new Empty Game Object.
\n– Create a new C# script called DrawLine2D \u200band put the below content in it:<\/p>\n
\nPress primary mouse button and move your mouse around screen, as you can see the line
\ngoes to draw lines in your mouse position. (Don\u2019t let the ball to fall)<\/p>\n
\nIn the code we first draw the line using mouse movement positions then we add the
\npositions to the LineRenderer component, then when the points added to LineRenderer, we use
\nthe points to Setup EdgeCollider2D points, so the ball will collide with the line as you can see in
\nthe above.<\/p>\n
\nThe above code mainly gathered from these sources:
