Simulate bomb throwing in top down game.

I guess you will have to use scale. set a variable called zscale set it at 1 and set scale of your bomb to that. When you throw it up scale will increase, then after a certain point start to decrease ( use gravity variable set at something like 0.02 )

So it would look something like this ( you will have to change numbers until it looks right, I have not actually tried it in a top down game )

After bomb thrown set power to 0.1

zscale = zscale+power

power = power - gravity

bomb set scale to zscale

Set limits so when zscale gets to 0.5 or wherever you want ground to be it bounces back by

if zscale<zscaleminimum power = power*-0.9

For direction of throw use angle of throw to set x and y direction. Similarly set xspeed and yspeed to increase like zscale and instead of gravity slow it down via drag variable, or something like that

There's lots of ways to do this. One way I like to do this is with Tween

Here's an example if you're throwing it to the left

tween "x" to self.x - 200 over 2 secs (linear)

tween "y" to self.y - 100 over 1 sec (out sinusoidal)

wait 1 sec

tween "y" to self.y + 100 over 1 sec (in sinusoidal)

the out sinusoidal followed by the in sinusoidal will give it a nice arc that looks like gravity

you can tweak these values until it feels right

You could do

On collision with wall
