How do I do a line attack.

Hi. I have a 16x16 grid, player moves by grid movement.

The green circle in the attached picture is the player. Trying to create a line attack (the yellow line) that extends out from the player and as far as the range (variable) of the line. In this case the range would be 4. If the mouse pointer is beyond the maximum range, the line draws towards the mouse but at the range number of squares.

Hope that makes sense

Sorry - to be specific i want to be the line drawn from the player to the mouse cursor.

Hey there, this is definitely not an easy task, but I might have an idea, I'll give it a shot when I have some time, unless someone bring a solution in the meantime

works almost perfectly, just gotta figure out how to make it so there isnt two squares beside each other so the line is only ever one square thick.

I though of doing something with points along the line, but didn't think it was going to work :P

I modified DiegoM example to get the result you wanted : drive.google.com/file/d/1osyoVyE536Zb4pf1I7THuT7STQ6YhgxZ/view

I changed and added a few things, everything is detailed in the project, don't hesitate to ask if you need more details ~

EDIT : I fixed a few things, notably a mistake that prevented to edit the range of the line

You, sir, are a wizard.

Thank you so much!
