Arcing Projectile

I have been scouring the forums and tutorials but have not found a way to make a projectile, eg. boulder, arrows, etc. fly with an arcing motion instead of the bullet motion.

Does anyone know a behavior that does this or is it in the physics?

You could use physics or you can set the gravity of an object with bullet behavior.

Even in a 3D Isometric view? I will post my example CAPX.

When you run it..

Click on the circular build spots to build towers.

The enemy will throw a boulder at a certain ActionPoint on their path.

That BOULDER is the item that I would like to see arc.

I will try the physics right now and see what happens.

Thanks.

Here is an example:

oh, it's great R0J0hound , anyway, onemore thing i want to ask you here, what about when i hold down the left mouse, the longer i hold, the farther (distance) the Projectile and shadow travel . :D

Use a variable as a charge-timer when mouse button is down, then set the bullet speed of the shadow object to the variable when mouse is released:

topview_projectile_charge.capx (r98)

If possible, think about the arrow like it having a shadow.

The distance between the arrow and the shadow is his height, so, to shot the arrow, it will have a arching trajectory, right?

Now, you'll need a math of this trajectory, the arrow will have mass and gravity, so, depending of the angle you shot your arrow, you'll need this math or something like it:

I did an arrow arching for a old RPG game have about 4 years, and what I remember is that I did an invisible shadow, who give the real trajectory and speed of the arrow, and an arrow flying, going up and falling relatively to the shadow.

thank Nimtrix, it's work .

R0J0hound Nimtrix this is awesome!! just what I was trying to do, thanks!!

Great example! Is it possible to drop the bullet at mouse click coordinates?

Can you share the math formula or diagram again ? It seems like the image is broken or something

Thanks

The university have moved it.
