How do I create a bullet movement with trajectory

I am trying to create the same concept from the link below in Construct2

http://gamemechanicexplorer.com/#bullets-5

I have found some examples on the forum but none is complete.

Three I am trying to accomplish here:

• Show trajectory
• Move through the trajectory
• Change bullet speed

Thanks,

Here's one for the physics behavior:

But you can do it without with simply:

global number gravity=1000

global number speed=200

global number step=0.1

global number vx=0

global number vy=0

global number x=0

global number y=0

every tick

--- dot: destroy

--- set x to cannon.x

--- set y to cannon.y

--- set vx to speed*cos(cannon.angle)

--- set vy to speed*sin(cannon.angle)

repeat 100 times

--- add gravity*step to vy

--- add vx*step to x

--- add vy*step to y

--- create dot at (x,y)

You example seems to be very simple but I not sure where to add things to.

Here is my capx for your reference https://www.dropbox.com/s/19z4n8iocakmxsq/trajectory-movement.capx

Also, can I change where the bullet start the movement (x,y)?

thanks,

I can't open your capx atm, but the every tick event is where you set the starting X,y, and velocities. In what I typed about it uses a object called cannon's position and angle.

Ok — I few more questions.

1) The ball should have which behavior?

2) what triggers the ball to start moving?

1) the bullet behavior would work fine.

2) just set the bullet's speed angle of motion and gravity, but you could do whatever.
