This a test project for the game to be called 'The fruit war', Drag the pineapple and shot it towards an apple structure located right beyond the screen. Click on 'REPEAT' to shoot again, or 'NEXT' to go to the next level.
Test 4: Level system. When pineapple enegy falls below a certain level the user can choose among two options: to go ahead for the next level or to start again. In the second case the score earned on the current level is divided by 2. Test 3: Decrease stiffness, masses and damping factor to get better convergence at larger time steps. Apple collision. Proved impractical. Test 2: Common integration procedure for projectile and structure, damage checking based on strain-stress state rather than force-displacement model. Test 1: Collision check to transfer energy of projectile to the structure. Test 0: Released as 'The Bridge Builder' game A predictor-corrector method of direct numeric intergration of motion equation with plastoelastic truss connections between masses in gravity field and gusts of wind.
