Maths Issues

[samcheung]

Hi, I am just so bad in maths. Now I got some problem when I'm writting a game in GE (actually it is a maths problem)
I am writting a game that the tank can specify angle and power. The bullet will base on those values to go up and down in parabola path.

I got a very simple formula "x = ay^2" but it's hard to relate to the angle. I think I may need some sin / cos formula???

I've seem the similiar game in GW Basic (~10 years ago) and it was my first favor-game!! Could anyone help me to solve this issue.... Thanks in advanced.

Oooh physical modelling. Yay!

Create an actor, call it bullet, and place it in the bottom left corner.

Now add a
create actor event
select script editor
and type

diretional_velocity = 25; // power of shot
angle = 65; // angle of shot

Add a
draw actor event
select script editor
and type

yvelocity += 1; // gravity

Run the game!

Hope this gets you started....

Cool man!! It is very simple and easy, now I can focus on the game logic.
Thanks!!
