Drawing an instant curved line

[Tobias_Edvardsen]

I am working on improving a throwing mechanic I have for my project. I've included an unlisted video (10 sec long) which demonstrates the current solution.

As seen in the video, the orange dotted line indicates the trajectory the thrown grenade will have. The orange dot object act the same way as the grenade, spawning every frame to give the illusion of a line, and is destroyed on collision with an obstacle. You may notice that upon pressing the throwing button, the dotted line has to travel from the player to the ground before illustrating a line, as well as readjust in the same pace if any mouse movement is applied.

What I would like is to replace this dotted line with a solid curved line that is instantly drawn upon pressing the throwing button. That way you can instantly tell where the grenade will land, regardless if you're moving the mouse.

I am unsure as to how to draw a curved line that will match the output of the thrown grenades physics. Does anyone have an optimal solution to this? Thanks!

si c'est une courbe calculée, pourquoi ne pas faire le meme travail dans une boucle rapide? si c'est un objet qui se deplace automatiquement avec un mouvement physique, c'est different

un peu comme ça?

Not exactly. I need the curved line to be updated continuously at all time. I'm not sure this is achievable by pasting the point object into background. In your example, would you be able to make it so the line is formed continuously while holding down the left mouse button?

This solution is applicable for my purposes! Thank you for helping out!
