HELP!!!!

[bexrazyallday]

Hey chili, I was going to make a game that involved a triangle spaceship that moved around and collected stuff. I am confused on how I get it to move as one object. As you will see that when you move around with the arrow keys, the triangle is there, but it doesn't move. All that happens is the line segment moves. Is there any way to make it all move as if it were one object? I am using your standard line drawing technique from your 10th video.

gfx.DrawLine(350,300,x,y,r,g,b);
gfx.DrawLine(350,300,400,250,r,g,b);
gfx.DrawLine(400,250,450,300,r,g,b);
gfx.DrawLine(350,300,450,300,r,g,b);

You're using your x and y variables for the first drawline only. The rest of them have their points hardcoded, so of course they won't move. You need to add x and y to each of the points of your shape.

I changed their values to the x and y, but it still gives me trouble. When I press any direction it all moves, but it changes shape and goes all funky. How do I fix that

gfx.DrawLine(350,300,x,y,r,g,b);
gfx.DrawLine(350,300,x,y - 50,r,g,b);
gfx.DrawLine(400,250,x + 50,y,r,g,b);
gfx.DrawLine(350,300,x + 50,y,r,g,b);

Apply it to the other side as well?
