How do I Draw a line

Hi all,

I would like to draw line across the screen with either touch or mouse.

I have searched for information to do this.

here;-

trying-to-draw-a-line-starting-from-the-point_t63632

Where an example is suggested but it doesn't seem to relate to drawing a line only creating a fixed line between two objects.

Kyatric who suggested the above example has a page of lots of techniques, this was the only one about drawing a line.

On another thread I found a decent explanation

how-do-i-draw-lines_t91464?start=10

but it was shut down for being too old.

I have managed to implement the technique given in that second link, thanks —, but while i can draw line, even a squiggly line, on release of touch or mouse, a line is continued from the last touch x, y to 0,0 and i can't understand why.

Does anyone have any ideas what could cause it?

I added this code to an already existing project, not a big project but with plenty of events. I have removed all the other stuff in this copy but i still get the line drawn on release.

Try this:

Note, that this method creates ~60 sprite instances every second, so don't make the sprite image too big and don't allow players to draw for too long without destroying old sprites.

Hi, thanks that's great it works!

Previously, i thought the problem was down to timing, release caused the touch X / Y to return to 0 before the line was finished drawing, right? I just didn't know how to solve that.

The actual sprite has a fade effect with Destroy on fade out, the debug view shows the objects increasing and decreasing quite well.

Thanks again.

I only have access to Construct 3 at the moment. But you can check this example to draw a line.

If you're using paster plugin you can paste the drawing on touch/mouse end, and delete all the sprites.

Edit: dop2000 works as well, but my example uses distance to create a uniform distance between the sprites, so you can have dotted lines etc. Also only creates as many as needed, based on distance.

tunepunk thanks, I've downloaded the file you attached.

I don't have construct 3 yet, I'm waiting to finish my current project, but I will take a look.

I recently developed a plugin do dynamicly draw lines (with dashed option). You can find it (with an exemple) on this links :

This is perfect for my project! Using a stretched sprite as a line looks horribly jagged, but this creates smooth lines AND they can be dotted! Thank you!!

instead of a sprite you can use a tiled background, which would be smooth no matter of distance stretched.

u can do a 2x2 pixel tiledbackground and then set the width height to whatever u want to do. make sure u have the origin point of the tiledbackground in the proper area, usually middle left or top left if middle left is not possible.

Sorry, just saw this. We solved the problem by using a bigger sprite, but this is good to know, thanks!
