Hi everyone,
i would like to know what are the common way to handle trajectory in a 2d
game. In fact, i think of writing a tower defense game and i wonder how to
handle the trajectory of the missile launch by the towers. I though of
getting the pos of the tower and the target and create a vector
It depends what you're trying to do.
If you draw the straight line between the tower and the enemy and use that
vector to translate a bullet each tick, the bullets might miss the enemy.
Think about it this way, the bullet moves 2 steps toward the enemy, then the
enemy moves 1 step, then the
Ok. But all the calcul of how long the bullet will take to reach the target
etc... will be made byn using vector? I mean, using a vector still viable?

Yes a vector is probably appropriate.

There is a pygame object to create a 2d vector?

No, but what you're talking about doing isn't hard. If you're having
trouble with it, you'll need to look into some elementary physics and
trigonometry.

Not built into pygame, but there is a good one on the pygame wiki:

You can define bullet speed in pixels per second.
You can use euclid (it works), but I instead suggest numpy. Which has a
vector( numpy.array ), and is useful for other game related things.
Here's a stand-alone example, uses numpy for vector movement.
Cool! I missed this email. I like the images, and diagrams.
Are you planning on ability to edit or create a new world?
Have you thought of doing a Terarria map viewer? (It's similar in a lot of
ways, but from the side view its 2d only.)
I found a few python interfaces to the map file:
