Jump to position (Worms style)

Question

Hey guys,

Currently working on a 3D side scroller and I'm trying to create movement for the player... kind of "Jumping" in the classic Worms games. So what I mean is, on button press the player needs to jump forward - let's say from Vector3(0.0, 0.8, 1) to Vector3(1.5, 0.8, 1) - in a parabolic fashion where it looks like that gravity makes sense. I will also need to be able to adjust the angle/duration of the forward jump/hop.

Your help will be greatly appreciated, have a great day.

try this video but change vector3.up to your own vector3. The positions of that vector three should be (0, 5, 5) I think. Sorry if I'm wrong, if I am I will look into it more. Here is the link for the YouTube video: https://www.youtube.com/watch?v=vdOFUFMiPDU

Wait how can you have a 3-D side stroller??

If it's like 2D in 3D then that probably won't work So I'll find a tutorial for 2D jumping so you can fix it either way.

Haha, I love that realisation part you had. Thank you for your answer, I will look into that video tomorrow and come back to either accept your answer or ask for more help.

The 3d side scroller thing might be a bit vague, but... yes I guess it is...

So I've just tested a few things but the problem with this is that your suggestion just lets a rigidbody jump with a specific force. Which give the effect of jumping I want, but it does not guarantee a location to land. I want to jump from the middle of the block to the next block and land in exactly the middle.

You'll either have to look into the math behind trajectory prediction, e.g how much force in which direction is required to land exactly at x coord. Or you could cheat and use a quadratic bezier to create an arc between two points.

Here's an idea I had, if it's a length of 1.25 from the middle of one ground tile to the middle of the next then what if you change the vector2 from (1,1) to (1,1.25) for example.

Wait no that's backwards I mean (1.25, 1)

Because if you do that then it should move 1.25 across the X axis which should do it so you could change the Y axis to whatever you want depending how high you want to jump.
