Forums → Programming Forum → why does my guy walk under the ground in my flash game?

there are a few other thread recently posted here regarding *collision detection* - basically this is what you need, you need to test points of the character and determine if it is hitting something, then respond to that - eg. make the player stop 'falling' through the ground and set it to that point

you probably either set the grounds registration point in the middle, or your character's image is actually lower than its registartion point, thus you end up walking on your knees:P

You just need to make the ground solid.

You need to put the Character's registration point low.

Mike, you'll have to give us more detail if you want us to help you. But it seems to be a deal with the collision... send us an image.

I think it's all about the registration point. I make that mistake a lot. And the title said "Walk under the ground". Plus the default registration point is in the middle, mike probably forgot to set it to low. Happens to everyone! Good luck.

@Bearsal1121,

that's in Game Maker. Adobe Flash is different.

Most probable reason: Wrong Registration Point.

Most probable reason: Wrong Registration Point

Either Registration point OR maybe you have your gravity too high, sometimes, if the gravity is too high, and you jump and the platform/ground isn't thick enough, your character falls through it because of the speed of the fall.

It is important to remember, there are many different methods to create platform-based games, so you may want to be more specific in future posts.

I highly recommend Tonypa's Tile-based tutorial:

This tutorial will take you through several types of tile-based games, including platformers.
