In game maker 7, my characters keep sliding slowly through walls. why?

FYI I have walls set to solid, the collision set with move to contact with the direction: direction and maximum 12 against solid objects. and the vertical speed at zero. please help!!!

Ok I guess you downloaded it if you didnt then you need to contact the makers. If you did download it then you need to download it again if it wasnt free then you need to contact the makers. if you got it off a cd uninstall it and then install it again. If you try all those things and they dont work just hope the makers will get onto a problem! I hope this has been good advice

I have no knowledge about your system but such problems are often hardware issues like the graphics card doesn't have enough memory, or the machine is too slow. Specifically, it sounds like the video isn't updating the image. If it's an older machine, that increases the likelyhood that's the problem.

Look at the minimum hardware requirements and make sure your machine meets or exceeds those requirements.

I'm assuming you're making a platform game.

First, see if the "Solid" box for the wall/ block object is checked (at the object properties).

Then, see if the actions for the player object (when it collides with the wall/ block object) are put in the right order: the "vertical speed" one should be under the "Move to contact" one.

If the first two didn't work out for you, you should try :
"Maximum= -1" at the "move to contact" action.
Maybe it's because in the Step event for your player object, you changed the maximum falling speed to a value higher than 12.
If (for example) you used 15 as maximum falling speed, then you should also put in 15 at the "move to contact" action (for when the player collides with the wall/block).

I hope this helped :)
