Grenades and Top Down 2D games

[DaUr3]

If I were to lob a grenade or to fire a mortar straight up and have it come back down, how do I make it not look like the grenade floats over certain blocks, how do I legitimately make it look like the flying grenade is moving closer to the camera and what not.

I kind of want my game to look like this drawing:

Thanks m8s.

Hi DaUr3,

You would need to calculate the parabola based on the start and end points. This means that you would have to create a middle point between points A and B which would be the parabola apex. And then interpolate using a quadratic equation.

This is a nice demo Parabola defined by 3 points | Desmos of what I’m talking about
And this explains how to do it: Writing Quadratic Equations

Alternatively you could use some tweening plugin from the Asset Store. Our spline system also does the job.
