i used game maker and i need help.

and also how do you make the character jump?

Sorry, if you read the rules of this board, you would realise that it is strictly for flash questions only. I am moving this to programming section. This shadow topic will be deleted shortly after...

Actually, it should be under Game Maker Help, a topic in this category.

Simple, just make an event that has an action that sets the vertical speed to a negative number and make it change to the jump sprite. also to prevent he character from jumping in mid air make it check if the floor object is below the character before it does those actions.

Question answered... besides, you can always ask this to Sirtopeia.
