To create more realistic jumping and maybe adding in trampolines/springs in a game, how would you do this by simply changing the value of a thrust variable?
Thrust and Jumping

You would have to change the thrust variable based on how how low the spring is. World 1 used animated springs, so they looked pretty bad, World 2 springs are done in code.
Doodle, sketch, draw, design, fill notebooks with elaborate scenes, funny character designs, and gameplay ideas.

You need to look into the idea of using velocity, then continuously adding to that velocity. A spring would set a very strong negative velocity (against gravity). So, in fakee code, you have:
springVelocity = -20;
//hero jumps on spring
heroVelocity.y += springVelocity;
//add the hero velocity to his position;
heroPosition.y += heroVelocity.y;A perfect book to get you started understanding simple physics is "Making Things Move" by Keith Peters. He has an AS2 and an AS3 version of the book.

Well the question is, how do you want the spring to react? If you want the character to move upwards immediately, then just like motionsmith said, even more simply, character.moveY = spring.thrust. Otherwise, well, that's a bit more code...

Yeah heh...i'm looking for a gradual gaining of energy. More realism
