Game maker 3.9.9? Is that a new or older version? (Or is that a completely different program?)

ill just... i dontt know... but when then forum reaches 10 pages, lets party!

uhhhhh geese.... when i push whether an object is solid or not its not solid... whats going on? i want it to be solid!

Is a newer version built specifically for mac and the creator of game maker is working on converting 3.7 to mac so mac users can use it.

if you want it to be solid you must go to that object itself for example a wall so just find that object and its on  the left side when you double click on it it should say solid and have a check box next to it.

...well, if what "Tha Man" said doesn't help...
If an object is not solid any collision checks will ignore it. If an object is solid collision check will check it along with everything else. i.e. if you have a ball that bounces on collision with any "Wall" or child of "Wall", and one of the children has Solid off, the one with solid off will never collide, so the ball will not bounce off of that type of wall. Or if you turn off Solid on the ball, the ball will not bounce at all.

Hope that helps.

also another thing you can do to make the object seem solid is have it to when it collides with object "wall" put a direction pad in it and click in the center and set the speed to 0

But you're game is going to look as best as others with different system.

ok, what im trying to say is that i DO check the boxes, but its NOT solid... i try to move though it when i did check it, but its still not solid...

Okay.
on the ball go
Add Event->Collision->Wall
then drag (it's something along the lines of) Bounce into the actions

That should work.
Checking Solid does not make you bounce off, it just makes it possible to detect if you have collided.
