So for a prototype I'm working on for a overhead shooter, I have the player controled by driving; that is forward, reverse, and turning. That was simple enough to do. What I want to have happen is to make sure the player can never move off-screen, or at least for now, not off the view.

I've tried a few things out short of writing a complicated series of conditionals, but none of them seem to work.

Using GM 8 Pro BTW.

Any guidance of any sort would be great. This is the last technical hurdle I have to push through; all the other mechanics are in place!

Does your view of the world move?

The simplest way would be to check the player's position in relation to the view's position:

Code:

if x < view_xview[0]                 x = view_xview[0]
if x > view_xview[0] + view_wview[0] x = view_xview[0] + view_wview[0]
if y < view_yview[0]                 x = view_yview[0]
if y > view_yview[0] + view_hview[0] x = view_yview[0] + view_hview[0]

No. It's stationary.

The simplest way would be to check the player's position in relation to the view's position:

Code:

if x < view_xview[0]                 x = view_xview[0]
if x > view_xview[0] + view_wview[0] x = view_xview[0] + view_wview[0]
if y < view_yview[0]                 x = view_yview[0]
if y > view_yview[0] + view_hview[0] x = view_yview[0] + view_hview[0]

I'm not sure I get what you mean. Your code snippet seems to reposition the player's position at either the x coordinate of the view or the x coordinate plus the width of the view, which is not what I want to do.

Perhaps if I rephrase. I want the boundaries of the view to act as though they were solid. Is this possible without creating objects?

If your view is stationary then this code is right, sort of. It should be this:

Code:

if x < view_xview[0]                 x = view_xview[0]
if x > view_xview[0] + view_wview[0] x = view_xview[0] + view_wview[0]
if y < view_yview[0]                 y = view_yview[0]
if y > view_yview[0] + view_hview[0] y = view_yview[0] + view_hview[0]

This resets the x,y coordinates of the object to the edge of the screen, which is what you wanted right?

[imaginationac]

Yes! That's precisely what I wanted! Thank you Theotherguy!

[pgil]

Whoops. Yeah, Theotherguy's code is what I meant.
