Hockey Game Boundary Collision Problems

By camsterb, with no replies.

Hi. I'm looking for a formula to use to change the trajectory of a hockey player bouncing and sliding around a rectangle through use of the inbuild move method. <Code Omitted> This method seems to work perfectly, but sometimes the player manages to get stuck beyond the boundaries. The object rotates left and right with keypresses. It moves in the direction in is facing. Maybe it's to do with turning the object while bouncing off a wall? Anyway, here is the link to observe what I mean: http://www.greenfoot.org/scenarios/7181 I'm looking for criticism of my method and advice to solve my problem of moving beyond boundaries. Thanks As an additional question: I want to be able to shoot the puck and give it the current rotation of the hockey player. This allows the puck to move that direction. I have some code already for this, but there are glitches. I will post more details at request. All the code is visible in the link.

Ctrl-Shift-I properly indents your code (it is the shortcut for Edit>Auto-layout within the code pane).

How is the world divided in cells? Problems with getObjectsInRange()

Last reply by JimmyFake, over 12 years ago:

I had some time, to try out what you posted danpost. My assumption was right, even though I may have expressed myself, incorrectly. For now the ObjectsInRange method works better for me, because an circular radius is fine for now, and the code is simpler. And thanks to GevaterTod, I do now know, how to use that command :) But if I want to adapt the area of the radius, because of some reasons that might appear in future, your advice would come in handy, danpost. Thank you both, again :D

You could set up an array to map the world. It could be of 'int', 'String' or 'char' type (guess it could even be of 'Class' type -- not that I would recomend it). This map could be used not only to create the initial background, but also to determine what is where during game play. Another possibility is to use color detection to determine what is where. This would involve breaking the color up into its primary color components and checking the values for certain ranges to distinguish between the different types of terrain (brown=mountain, blue=water, tan=dirt, green=grass
