Collision detection between player and platform

[jammas615]

I have a simple platform game that allows the player to jump onto platforms and climb a tower. It is essentially vertical scrolling. I have run into a wall trying to figure out how i can detect a collision between the player and a block.

My basic problem is trying to figure out how i can have many blocks drawn to the screen and detect if the player is touching one or more individual blocks.
Does each block need an id and then i check each block for collisions? (that would just be a waste of resources and time!)

Any ideas?

I'm assuming that your gui or "view" has an underlying non-gui model that it's based on, and if so, all collisions should be analyzed there, not in the GUI section of the code which simply displays what the model tells it to display.

Okay. I have a block class that contains the data for each block that is drawn. When a map or platform is draw a random number is generated, this number is fed into a loop that draws a new Block() each time. Is there a better way to do that? Especially when it comes to detecting collisions.
