Problem with velocity

Games
#1

In code bellow ball falls in required point on ground but with small velocity. How to increase ball velocity with saving target point? Help please.

[code]
physics = require(“physics”)
physics.setDrawMode( “hybrid” )
physics.start()

ground = display.newRect(0, 0.75*display.contentHeight, display.contentWidth, display.contentHeight/4)
physics.addBody(ground, “static”, {friction=2})

ball = display.newCircle(40, 0.75*display.contentHeight-8, 8)
ball:setFillColor(255,0,0)
physics.addBody(ball, {friction=1, radius=8})

ball:setLinearVelocity(100,-200)

How about this (or you could play with the gravity setting) :

[code]
physics = require(“physics”)
physics.setDrawMode( “hybrid” )
physics.start()

ground = display.newRect(0, 0.75*display.contentHeight, display.contentWidth, display.contentHeight/4)
physics.addBody(ground, “static”, {friction=2})

ball = display.newCircle(40, 0.75*display.contentHeight-8, 8)
ball:setFillColor(255,0,0)
physics.addBody(ball, {friction=1, radius=8})

ball:setLinearVelocity(100,-400) – change the second value to increase the speed

If I will do it, target point (point where ball collide with ground after motion) is changed. And I need to save target point coordinates. Changing gravity doesn’t help because ball flies farther. [import]uid: 86894 topic_id: 15568 reply_id: 57485[/import]

Ok. Do you want to stop the ball when it hits the ground ? [import]uid: 84637 topic_id: 15568 reply_id: 57486[/import]

No. In my code ball hits the ground (after arc motion) in specified target point. Everything is good, but I do not like movement velocity. I need to increase velocity but my specified target point should not be changed. [import]uid: 86894 topic_id: 15568 reply_id: 57487[/import]
