Ethernet Posted October 21, 2019 Share Posted October 21, 2019 (edited) Hello. I trying to make 3D throw for my bullet script. On X and Y axis is okay, but idk how to calculate Z axis. This script should work like this: But works like this: My code: x = x - math.sin ( math.rad ( rotationZ ) ) * 0.1 y = y + math.cos ( math.rad ( rotationZ ) ) * 0.1 --x1 = x- math.sin ( math.rad ( rotationZ ) ) * 4 --y1 = y + math.cos ( math.rad ( rotationZ ) ) * 4 z = ? What calculations I must use on Z axis? Thanks! Edited October 21, 2019 by Ethernet Link to comment

Ethernet Posted October 22, 2019 Author Share Posted October 22, 2019 Thank you, but it's not solved my problem. Maybe other solutions? Link to comment

Discord Moderators Zango Posted October 23, 2019 Discord Moderators Share Posted October 23, 2019 You need more than just rotationZ to do that, if you want to find a point from the rotation of the gun. Assuming your weapon has a pitch and yaw, and roll is 0, you would do this to find your point, where yaw is your rotationZ (in radians) x = x + 0.1 * math.cos(pitch) * math.cos(yaw) y = y + 0.1 * math.cos(pitch) * math.sin(yaw) z = z + 0.1 * math.sin(pitch) Link to comment
Ethernet Posted October 25, 2019 Author Share Posted October 25, 2019 Okay, thanks Zango, but what's pitch?

Discord Moderators Zango Posted October 25, 2019 Discord Moderators Share Posted October 25, 2019 It's the angle your gun is tilted upwards in your picture. Like this rx, ry, rz = getElementRotation(gun) rx = math.rad(rx) rz = math.rad(rz) x = x + 0.1 * math.cos(rx) * math.cos(rz) y = y + 0.1 * math.cos(rx) * math.sin(rz) z = z + 0.1 * math.sin(rx) What is your gun, is it an object or a custom weapon? It might be better for you to use a matrix, see the example in getElementMatrix 1 Link to comment
