Trajectory Calculator for GMS2

Introducing the box2d trajectory calculator!

This is a calculation script, made entirely for GameMaker's built-in physics engine, Box2D.

With this you could predict how a projectile will fly before it starts flying, like in that bird game.

What can it do?

• It can predict the parabola path of any physics bodies.
• It can predict the max height & distance the projectile will reach.
• It supports collision detection during the calculation. 
• It supports the "linear damping" property and is aware of the speed limitations of box2d physics.
• It supports the world x/y gravity & pixel-to-metres properties of box2d physics.
• Each script comes with detailed commentaries for how to use

With all those information gathered, you can use them in various ways to your advantage: 

• Render a predicted parabola for your tanks and weapons
• Instantly know where a projectile will land, without actually firing it and waiting for it to land
• Get a predicted coordinate of the point of impact with any physical objects, with the script's collision detection ability
• And much more, with your own creativity...
