is it possible to make a rectangle with the draw_rectangle function, that will be solid(like an instance)?

thanks!

Yes, just set the last argument to false.

For the record, you should always check the manual for these sorts of things - it will show you what all the arguments for each function do, and give you some code samples.

i'm sorry, i was unclear. i ment solid, like an instance. a thing you can collide with

Welcome~

Please provide more information on what you are trying to do. As a rough idea, you want to check for collisions with an instance. If it is so, you can use point_in_rectangle() and give it the parameters that you used in the draw_rectangle() call. For instance, if you drew a rectangle between (200, 200) and (400, 450), you may do this:

Code:
if (point_in_rectangle(obj_player.x, obj_player.y, 200, 200, 400, 450))
{
    // ...
}
Again we can't give an accurate response unless enough information is provided. :)

thank you very much!
 
You can also use an invisible instance (for example, the one that's doing the drawing of the rectangle!) and use 'image_xscale' and 'image_yscale' to make it be the size of the drawn rectangle. For example:

For this example, the mask of the instance will be 32x32 in size.

Create Event:
Code:
// The size of the drawn rectangle
size_x = 512;
size_y = 64;

// Ideally, you'll either want to create a constant for the '32' value, or use 'sprite_get_width/height' to dynamically obtain the value, but this is just an example
image_xscale = size_x / 32;
image_yscale = size_y / 32;
Draw Event:
Code:
draw_rectangle(x, y, x + size_x, y + size_y, false);
... And that's it! You should be able to collide with your drawn rectangle as if it were a normal instance with a sprite. You can even make it change size by updating the image scaling values in the step event.
